MODELLING SUNSEEKER PREDATOR YATCH USING SOLIDWORKS

INTRODUCTION :

SOLIDWOKS: Solidworks is one of the most used CAD programs in professional settings across the globe. This software is mainly used to create 3D model parts using 2D sketch. It also has the feature to assemble the parts that we designed into a complete model. It also has another add-in feature like Photoview 360 which helps in rendering the final model to make it look in realistic. In this project learned about the detailed design of Yatch parts and Assembling them.

Version used in this Project is Solidworks 2020.

YATCH: A yacht is a sail or power vessel used for pleasure, cruising, or racing. There is no standard definition, so the term applies to such vessels that have a cabin with amenities that accommodate overnight use. To be termed a yacht, as opposed to a boat, such a pleasure vessel is likely to be at least 33 feet (10 m) in length and may have been judged to have good aesthetic qualities.

OBJECTIVE :

The main objectives in this projects are,

• To know about the blueprints of Sunseeker Predator Yatch.
• To create individual parts of Yatch using Solidworks.
• To assemble all the individual parts into a Sunseeker Predator Yatch.
• To the applications of Decals, Rendering, Camera etc.

DESIGN FLOWCHART :

TOOLS AND FEATURES :

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. It transforms rotational power into linear thrust by acting upon a working fluid, such as water or air. The rotational motion of the blades is converted into thrust by creating a pressure difference between the two surfaces. A given mass of working fluid is accelerated in one direction and the craft moves in the opposite direction.

Features used to create Propeller:

• The propeller is modeled simply by using solid modeling features such as - Revolved Boss/Base,Extruded Cut, etc.
• Initially, a single blade is modeled using the Lofted Boss/Base
  It is then using in the Circular Patternfeature to model the rest of the blades.
• Filletsare added to remove off the sharp edges, provide appropriate curvature to the periphery of the blades and improve the outlook of the propeller.

Radar: Radar is a vital navigation component for safety at sea and near the shore. Captains need to be able to maneuver their ships within feet in the worst of conditions and to be able to navigate "blind", when there is no visibility at night or due to bad weather.

Features used to create Radar:

• The Radar is modeled very easily using the following features - Extruded Boss/Base, Cut Extrude, Fillets, etc.
• Since, the radar is symmetric in shape, only haf the portion is modeled.
  The other half is simply mirrored using the Mirror The Merge Solidsoption is enabled while doing so.
• A text is added on the surface just for the sake of a better and realistic outlook.
  The text feature can be found at the mentioned path: Tools- Sketch Entities - Text.
• This text is then projected on the radar surface using the Split Line

Blueprint Setup: For Designing any components blueprint is must for reference.

Features used to create Blueprints Setup:

• All the blueprints were imported into a SolidWorks part file using the path : Tools - Sketch Tools - Sketch Picture.
• Appropriate positioning as well as scaling of the blueprints is very important and has to be done perfectly as shown.
• This Blueprint setup is then used to model all the parts.

Hull: A hull is the watertight body of a ship, boat, Yatch or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. At top 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.

Features used to create Hull:

• The hull is essentially modeled by Surface Modeling.
  The outer surfaces of the Hull are created using the features in the Surfaces tab.
• For this, the Project Curve feature along with the different sketch tools, is used to create the outer peripheries of the surfaces.
  Then, the surfaces are created using these curves and by using features such as Lofted Surface, Boundary Surface, Extruded Surface, Trim Surface, etc.
• The Port Holes are modeled by using the Swept Boss/Base features after using Extruded Cut.
• The railing is modeled by creating projected curves through different sketch tools and then by using the Swept Boss/Base command with the curves as the sweep path.
• Fillet is used at all the required places where sharp edges are to be avoided. Also, providing fillets around the windows gives a good aesthetic appeal to the model.
• The Anchor is modeled directly as a solid i.e by using the features such as - Extruded Boss/Base, Extruded Cut, etc.
• These two symmetric parts are then carefully knitted together using the feature Knit Surface.
  The Create Solid option is enabled to fill the inside portion of the Hull.
  While doing so, it is ensured that the knitting is done properly. This can be done by carefully looking at each and every edge. A perfectly knitted edge looks black in colour, while a blue edge means that there is no association between the two faces altogether.
• To give a more realistic outlook, decals are added on the deck surface as well as the stair surfaces.
• Since, the Hull is symmetric, only half the portion is modeled, the rest half is mirrored using the Mirror feature.

Garage Door: Covers the garage space in the yatch as door.

Features used to create Garage Door:

• The Garage door is simply modeled using the garage portion which was carved out of the Hull.
• The unnecessary portion is removed off by using the Extruded Cut feature.
  Fillets were provided to blend the sharp edges.

Seats:

There are three seating in the model - Front, Middle and Rear.

1.Front Seat

2.Middle Seat

3.Rear Seat

Features used to create Seats:

Extruded Boss/Base, Cut Extrude, Fillets, etc.

• Here, the Front and the Rear seats are modeled by first creating the outer surfaces using the features of the Surface Then by creating a solid after carefully knitting the surfaces together using the Knit Surfacefeature.
• Filletis used at all the required places where sharp edges are to be avoided.

Superstructure: A superstructure is an upward extension of an existing structure above a baseline.

Features used to create Superstructure:

• The Superstructure is also modeled by creating the outer surfaces first, just as we did in the case of Hull.
• These surfaces are then mirrored using the Mirror command and then knitted together properly with the Knit Surface.
• Here as well, the railings are modeled by using the Swept Boss/Base feature.
• The Jacuzzi is just a cutout with a surface at the top to represent the water-level.
  The surface is given a transparent appearance for this purpose.
• The window edges are blended using the Fillet feature to give a smooth appearance.
• The vipers are modeled using solid features such as Extruded Boss/Base, Extruded Cut, Swept Boss/Base, etc. along with appropriate Chamfers and Fillets.

Radar Mast: The Mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat. Its purposes include carrying sails, spars, and derricks, and giving necessary height to a navigation light, look-out position, signal yard, control position, radio aerial or signal lamp.

Features used to create Radar Mast:

• The Mast consists of 2 light bulbs along side 2 antennas.
• This mast is easily modeled using the solid features such as Extruded Boss/Base, Revolved Boss/Base, Swept Boss/Base, etc.
• The horns are modeled by using the Shell feature. This feature essentially removes off the inside material out of a solid 3D part, thereby making it hollow.
• The Mirror feature is used to mirror symmetric entities

Assembly:

• All these individual parts are then assembled together using the SolidWorks Assembly file.
• First off, the Hull is fixed at the proper location.
  Rest all the parts are then located with respect to this fixed Hull.
• Standard Mates such as Coincident, Tangent, Concentric, Parallel, etc are used to provide appropriate constraints.

Features Tree of Assembly:

Rendeirng:

• The Yacht Assembly is rendered using the Add-In SolidWorksVisualize tool provided by SolidWorks.
• Proper Scene is created for the rendering.
  Appropriate Environmentis set up for this purpose. Also, a suitable Backplate is chosen out of the library.
• Camera is set up by providing appropriate location.

The Perspective view is enabled to ensure real-time look.
