MODELING OF COMPONENTS AND ASSEMBLY & RENDERING OF SUNSEEKER PREDATOR YACHT USING SOLIDWORKS

Introduction:

         This report contains of modeling and assembly of SUNSEEKER PREDATOR YACHT components and final rendering with detailed explanation using the solidworks software.

Objective:

• The objective in the project to learn and understand the different tools and commands in solidwoks.
• How to model different components in part option.
• How to assemble the various components together in assembly option.
• How to render the assembled YACHT and make realistic view image in solidworks visualize.

Part modeling:

             In part modeling the following plane has to be selected & sketch the model on the selected plane with following dimensions.

Blueprint setup:

           The Blueprints setup is used as a reference to allocate the position of the yacht. The height, length and width of the Blueprint is the same as that of the yacht model. There are 5 Blueprints9(planes) used in the design of the yacht. The first hull part is made up by using this Blueprint and after that all the other parts are designed.

• Rear_view Blueprint (Back plane)
• Bottom_view Blueprint (Bottom plane)
• Front_view Blueprint (Front plane)
• Side_view Blueprint (Mid plane)
• Top_view Blueprint (Top plane)

Parts modeled for Sunseeker predator yacht:

• Propeller
• Radar
• Hull
• Garage Door
• Front Seat
• Middle Seat
• Rear Seat
• Superstructure
• Radar Mast

1.Propeller:

           A propeller is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral, that, when rotated, performs an action which is similar to Archimedes' screw. It transforms rotational power into linear thrust by acting upon a working fluid, such as water or air.

Explanation:

          Propeller is sketched by line, Circle, 3 Point Corner Rectangle  & Spline. Then they are Revolved Boss/Base, Extruded Cut, Circular Driven Pattern, Lofted Surface, Plane & fillet at the edges and we gave them appearance. Finally, they are rendered by Photo view 360.

Features used:

• Sketch
• Revolve
• Loft
• Fillet
• Mirror
• Cut extrude

Sketch:

        The sketch is the basis for a 3D model. ... You can create a sketch on any of the default planes (Front Plane, Top Plane, and Right Plane), or a created plane.

Revolve:

        Revolves add or remove material by revolving one or more profiles around a centerline. You can create revolved boss/bases, revolved cuts, or revolved surfaces. The revolve feature can be a solid, a thin feature, or a surface.

Lofted surface:

         Lofted surface is a 3D surface that is defined by two or more NURBS curves. The surface intersects the curves in given order.

Fillet:

        Fillet/Round creates a rounded internal or external face on the part. You can fillet all edges of a face, selected sets of faces, selected edges, or edge loops.

Mirror:

           Mirroring is another way that SolidWorks can create a “copy” of an existing object. Additionally, you must choose a plane to mirror parts. In most cases, you will have to create your own plane to have the mirror done the way you need.

Cut extrude:

        The Extruded cut operation allows you to easily remove material from a solid by extruding a profile along the normal to its plane.

2.Radar:

        Radar (Radio Detection And Ranging) is a detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.

Explanation:

             For the construction of Radar, Sketch is made on the Right Plane and Extruded to the given dimension. Using Offset entities another sketch is made and again uses the extrude boss feature to get the corner of Radar. Cut Extrude is used to get screws on the end of the cornered surface of Radar. Sketch pattern feature is used to lock the position of other 3 screws. Mirror feature is used to get the exact Radar. White colour is preferred as appearance for the radar and fillets are added to give smooth curves. Finally the modeled component is rendered.

Features used:

• Extrude
• Fillet
• Cut extrude
• Sketch pattern
• Mirror
• Split line
• Sketch text

Extrude:

             The extrude tool can be defined as a tool that duplicates the selected vertices, edges, and faces, connecting them to the original model in series of the original vertices, edges, or faces. ... This tool is useful for creating more vertices for better and more specific modeling.

Sketch pattern:

       The Curve Driven Pattern tool allows you to create patterns along a planar or 3D curve. To define the pattern, you can use any sketch segment, or the edge of a face (solid or surface), that lies along the plane. You can base your pattern on an open curve, or on a closed curve, such as a circle.

Split line:

       The Split Line. tool projects an entity (sketch, solid, surface, face, plane, or surface spline) to surfaces, or curved or planar faces. It divides a selected face into multiple separate faces.

Sketch text:

            Sketch text on any set of continuous curves or edges (including circles or profiles made up of lines, arcs, or splines on the face of a part) and extrude or cut the text.

3.Hull:

             A hull is the watertight body of a ship or boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline.

    Hulls come in many varieties and can have composite shape, but are grouped primarily as follows:

• Chined and hard-chined. Examples are the flat-bottom (chined), v-bottom, and multi-bottom hull (hard chined). These types have at least one pronounced knuckle throughout all or most of their length.
• Moulded, round bilged or soft-chined. These hull shapes all have smooth curves. Examples are the round bilge, semi-round bilge, and s-bottom hull.

Explanation:

                 First, the blueprints of all the views are placed in the environment. Using these blueprint as a reference create the surface bodies of the hull. Then using the knit-surface feature, convert the surface bodies into solid objects. Once the solid model is formed all other hull features are created using extruded boss, extruded cut, revolved boss, and sweep boss. Ropes for anchors are created using helix and sweep features. Railings and the curved surfaces of the hull are created using the projected curve option. The split line option is used to create a split appearance on the outer surface of the hull. The garage space is created using the split option. The body consumed while creating the garage space is saved as a garage door. A surface is created using the offset surface feature by keeping the offset distance as zero. This surface appears to be hidden on the deck of the hull. This surface is used as a reference for seat modeling. Decals are used on the deck of the hull, stairs, and on the floor of the garage space.

Features used:

• Sketch
• Projected Curves
• Linear Pattern
• Mirror
• Surface Extrude
• Surface Loft
• Extrude Cut
• Fillet/chamfer
• Sweep
• Surface Knit
• Surface Trim
• Offset surface
• 3D Sketch
• Shell
• Helix/spiral

Projected curves:

          Project a sketched curve onto a model face to create a 3D curve. You can also create a 3D curve that represents the intersection of two extruded surfaces generated by creating sketches on two intersecting planes. You can create multiple closed or open-contour projected curves from a single sketch.

Linear pattern:

      Linear patterns to create multiple instances of one or more features that you can space uniformly along one or two linear paths.

Surface extrude:

      Create extruded surfaces from models that include 2D or 3D faces and knit the extruded surfaces to surrounding features.

Sweep:

       SWEEP is the one feature in Solidworks that helps sweep a closed profile along a closed or open path. In this session, we are going to use a simple 3D object as an exercise to demonstrate the use of the SWEEP command in Solidworks.

Surface knit:

       The Knit Surface tool to combine two or more faces and surfaces into one. ... Knit surfaces absorb the surface bodies you used to create them. Create a solid body when the knit surfaces form a closed volume, or leave as a surface body. Select Merge entities to merge faces with the same underlying geometry.

Surface trim:

        Use a surface in conjunction with additional surfaces, as mutual trim tools. Trim surface includes the following options: To trim a surface: Create two or more surfaces that intersect at one or more points, or create a surface that intersects with a plane or has a sketch on its face.

Surface offset:

       A common technique for advanced surfacing modeling is using the Surface Offset command. In SOLIDWORKS 2020, the command gives users the option to SEE and REMOVE any surfaces that cannot be offset, building the remaining geometry.

3D sketch:

         create a 3D sketch with reference to XY, YZ, and ZX planes, axes, or surfaces.

use 3D sketches in applications such as SOLIDWORKS Weldments to insert structural members along a 3D frame, for routing paths, and to reverse engineer meshes into solid parts.

Shell:

       The shell tool hollows out a part, leaves open the faces you select, and creates thin-walled features on the remaining faces. If you do not select any face on the model, you can shell a solid part, creating a closed, hollow model. You can also shell a model using multiple thicknesses.

Helix/Spiral:

        The Helix and Spiral tool can be cleverly used to generate 3D curves which can be then used as a sweep path. Ideal for creating springs! The tool will create your desired helix or spiral based on an initial circle sketch and definition values e.g. Pitch and Number of revolutions.

4.Garage door:

       A garage door is a large door on a garage that opens either manually or by an electric motor (a garage door opener). Garage doors are frequently large enough to accommodate automobiles and other vehicles. Small garage doors may be made in a single panel that tilts up and back across the garage ceiling.

Explanation:

           This part of the hull is consumed using a split feature which is used to create a garage door. First, the unnecessary part of the garage door is removed using an extrude cut feature, and then it's made hollow using a shell feature. As the door is symmetric about the midplane, we will create half portion of the door and then the other half will be mirrored. Fillets are provided at all the required edges. A text is created on a separate plane and then projected on the garage door with the help of extrude cut feature.

Features used:

• Extrude cut
• Shell
• Save bodies

Save bodies:

       The Split feature to create multiple parts from an existing part. You can create separate part files, and form an assembly from the new parts. You can split one or more solid or surface bodies.

5.Front seat:

       It is comparatively easy to model and requires less time. It is arranged at the front finish of structure with the goal that individuals can appreciate the view while cruising on yacht.

Explanation:

         First, the insert part option is used and only the surface bodies of the hull part are inserted for reference. All the surfaces are created with the help of blueprints. The seats are symmetric about mid-plane so half the part will be created by surface modeling and other features, and the other half will be mirrored. The model will be converted into solid bodies using a knit surface. To create pillows offset and revolve boss feature is used. The Dome feature is used to give a curvature effect to the pillows. It is rendered finally.

Features used:

• Surface sweep
• Surface extrude
• Surface knit
• Surface trim
• Surface loft
• Fillet
• Chamfer
• Revolve
• Mirror
• Dome

Dome:

            The software calculates the distance using the radius of the arc as a basis for the dome. It creates a dome that is tangent to the adjacent cylindrical or conical face.

Surface sweep:

      Sweep Surfaces are surfaces that are generated from a section curve positioned along a path. ... Parallel Sweep is defined as a section curve moving along a guide path while maintaining the section curve to be parallel to the guide path.

6.Middle seat:

       This seat is situated behind the superstructure. It is also used to sit and enjoy the moments.

Explanation:

       Open the blueprint setup and  open the surface body from the  hull. Create a top plane and Backplane using the front and bottom plane as a reference.  Insert hull part which we have saved as a deck surface for the reference.Draw a L Shape using lines on face of deck and extrude for lower portion of seat.Create a sketch on above extrude face offset the face and extrude. Create a Plane on above extrude face by offsetting at a distance of 5mm. Sketch on it by drawing lines as per blueprint and extrude. Mirror the bodies across Mid Plane by selecting Knit Surfaces and merging solids. Mirror seats across Mid Plane by de-selecting Knit Surfaces and Merging solids. Create a Table by selecting the deck face using lines and offset entities. Create a Cut Extrude at the top surface of the table and apply fillets. Finally give Appearance to Table & Seats.

Features used:

• Extrude
• Chamfer
• Cut Extrude

7.Rear seat:

        Rear seat is situated at the rear end of Hull which is also used to sit and enjoy the moments. Seatsand chairs can be used on the fast ferry, high-speed passenger ship, cruise ship, catamaran, crew boat,, cargo ship, the sightseeing ships for sitting purposes.

Explanation:

          The design methodology is same for the middle seat as well: Use the top and side blueprints and the hull surface--> MAKE the sketch-->add dimensions-->add fillets and chamfer-->mirror the seat and form the solid body.

Features used:

• Surface sweep
• Surface offset
• Surface trim
• Surface knit
• Surface extrude
• Surface loft
• Surface extend
• Ruled surface
• Chamfer
• Extrude
• Fillet
• Sweep
• Surface fill

Surface extend:

         Extend a surface by selecting an edge, multiple edges, or a face. For edges, the surface extends along the plane of the edge. ... For faces, the surface extends along all edges of the face except those connected to another face.

Ruled surface:

          The Ruled Surface command creates surfaces that extend out in a specified direction from selected edges. Examples of how you can use ruled surfaces: Add tangent extensions to complex surfaces. Create drafted sidewalls.

Surface fill:

          The Filled Surface feature constructs a surface patch with any number of sides, within a boundary defined by existing model edges, sketches, or curves, including composite curves. You can use this feature to construct a surface to fill a gap in a model.

8.Superstructure:

      A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships having the degree of freedom zero 

Explanation:

              First, the hull surface(i.e deck surface) is imported that forms the base for creating the superstructure of the yacht. Features used for modeling are surface extrude, extend surface, lofted surface, knit surface, offset surface, filled surface, trim surface. Projected curves are developed for creating surface bodies.

               One section of the model is created and the remaining section will be mirrored about its midplane. The final surface body will be converted into a solid body. Other detailing will be done using the boss extrude and extrude cut feature. Lastly, a surface is created using the offset surface feature with zero offset distance at the top of the superstructure. This surface is used as a reference for creating a radar mast.

Features used:

• Surface Extrude
• Sweep
• Knit
• Ruled Surface
• Surface trim

9.Radar mast:

        Each unit has a waterproof radar cable gland positioned aft and below the top plate. ... Unlike our Power Mount Plus these Standard Mounts are not Light/GPS Bar capable.

        Marine radars are X band or S band radars on ships, used to detect other ships and land obstacles, to provide bearing and distance for collision avoidance and navigation at sea. ... Therefore, displays can often overlay an electronic GPS navigation chart of ship position, and a sonar display, on the radar display.

Explanation:

      Use the superstructure surface and import it in the sketch. use the side and the top blueprint to make the radar mast. First make the base of the radar mast and extrude the base. Then Create the antenas using circle and extrude. Mkae the support for the radar. make a profile for the horn and use revolve to amke the horn. use shell command to make the horn hollow, mirror the horn. Make the profile of the two structure and use revolve to create the part, finally use mirror the entire part except the horn.

Features used:

• Extrude
• Revolve
• Plane
• Sweep
• Chamfer/Fillet

Assembly of Yacht:

                        For assembly of YACHT open the new assembly file. Now insert the modeled parts  of the yacht. First we have insert chassis in correct position. With the reference of Hull assemble the other parts one by one using the mates.

Mates: Mates create geometric relationships between assembly components. As you add mates, you define the allowance directions of linear or rotational motion of the components. You can move the components within its degrees of freedom, visualizing the assembly`s behavior.

• Mates used to assembly of Yacht such as:
• Coincident
• Concentric
• Distance
• Limit angle
• Width
• Angle
• Parallel
• Tangent
