RADAR MAST & FINAL ASSEMBLY USING SOLIDWORKS

Modeling and final assembly of Sunseeker Predator Yacht

Introduction:

In this project, we will discuss detailed Modeling of Sunseeker Predator Yacht by using SolidWorks software & Photo-Realistic Rendering of our final assembly by the use of Solidwork Visualize. Solidworks is one of the most use software for solid modeling, creating 3D parts from 2D Sketches creating mechanisms doing simulation, and much more. It is a handy tool to work on complex geometries to create 3D solid parts with exclusive Features & tools to work on your geometry and create your imagination in reality great software to create models which are endeavors. Sunseeker is a British organization that is masters in creating luxurious yachts and speedboats. So, in this project, we will do complete part modeling of this yacht and do the final assembly.

• Objective:

The main objectives of this project are

1. To create Individual Part modeling of Sunseeker Predator Yacht by use of Solidworks
2. To Assemble these Parts of the yacht to get our final complete assembly of predator yacht
3. To give appropriate appearances and looks to our final model by use of scenes, camera view, textures
4. To create the photorealistic model and render it using photo view 360 & Solidworks Visualize

Design Methodology of Sunseeker Predator Yacht :

Blueprint Setup:

To start with our modeling first we need to set up a working environment for our yacht this can be done by using Blueprints.

Blueprint: Blueprint is an interesting technical way of showing the design of the conceptual work with details that can be understood by all the technical staff within the team to create the component. This is used in almost all the engineering fields and to explain the details of the workflow and components. This concept was introduced by John Herschel in 1842. It is a detailed document to understand the different technicalities of the construction of the project. So, blueprints play a crucial role in the development of any new component in our yacht case also we are setting the blueprint set up to start our modeling.

Procedure to be followed for setting up Blueprint:

• First, open a new part file in Solidworks software.
• Before creating Sketch changed the default name of planes as follows:

1) Front Plane- Front Plane

2) Top Plane- Top Plane

3) Right Plane- Mid Plane

• Now select the Front Plane and start sketching on it go to tools> Sketch tools> select sketch picture option and open the front view blueprint image

• Give appropriate dimensions to the blueprint image so that to position it properly and select the full image option changing the transparency to 0.43 click ok

Follow similar steps to setup other blueprints and complete the setup as shown below

Once we have finished the blueprint setup we can now proceed with the first part model that is the Propellor

Propellor:

This is the important component of the yacht as it is used to propel i.e to move the yacht by forcing the water in the backward direction by rotational motion of the propellor consist of several curved vanes all over the body of the propellor which when rotates forces the water in the backward direction their by producing a thrust force acting in backward direction and the yacht moves in forwarding direction.

Features use to create Propellor:

• Sketch
• Revolve
• Cut-Extrude
• Loft
• Fillet
• Circular Pattern

Sketch: To start with our model we have to create our sketch for the propellor.

The Sketch is the 2D representation of the model which afterward gets transformed into the 3D object in Solidworks there are different sketch entities provided to draw our sketch such as line, Rectangle, spline, circle, arc, etc.

Revolve:

This feature is used to sweep a sketch entity, profile along with an axis or centerline at a 360-degree angle to give a solid part or model.

Cut-Extrude:

This feature is used to remove unwanted material from our solid body to give us the required part or model.

Loft:

This feature is used to add material between two or more sketch profiles to form a solid feature.

Fillet:

This feature is used to create round internal or external faces by selecting edges, faces of a solid body, or surfaces.

Circular Pattern:

This feature is used to create a pattern of the selected entity against a circular path we can provide an angle in between two entities which are patterns along a circular path in the case of our propellor we have created a circular pattern of our vanes.

Procedure to be followed to create Propellor:

• First, open a new part file in Solidworks
• Then select the front plane from the feature tree and Start sketching on the front plane.
• Use sketch entities such as line, spline to draw the sketch and give dimensions and necessary relations to the sketch to make it fully defined.
• Once the sketch is completed then select the revolve feature to create revolve.
• Select the top plane for sketch and draw a rectangle on a top plane after that create a new plane by offsetting the top plane.
• Create another rectangle on this new plane and select the loft feature in that select the two rectangle sketches to create a loft.
• Give fillet to edges of the lofted rectangle to create a smooth curve vane.
• Remove unwanted material by applying the cut-extrude feature.
• Then do a circular pattern of the vanes created.
• Lastly, save the model with the name "Propellor".
  

Radar:

Radar 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. So, this radar acts as a navigator for our yacht as it shows different objects which remotely located from our ship or are underwater.

Features use to create Propellor:

• Sketch
• Extrude boss
• Cut-Extrude
• Fillet
• sketch Pattern
• Split line
• Mirror

Procedure to be followed to create Radar:

• First, open a new part file in Solidworks.
• Then select the Right plane from the feature tree and Start a sketch on the right plane.
• Use sketch entities such as lines to draw the sketch and give dimensions and necessary relations to the sketch to make it fully defined.

• Once the sketch is completed then select the extrude boss feature and extrude the sketch then provide necessary fillets to it.

• Draw another sketch by selecting the extruded surface as shown above and complete the sketch.
• Once the sketch is completed create another extrude boss by selecting the previously drawn sketch on the face of extruding.
• Create another cut extrude as shown below by drawing a polygon.

• Now select the Sketch-driven pattern option from the features tab and complete a pattern.
• Select the mirror feature to select the right plane as the mirror plane along which the mirror will create.
• Select the split line option from the curves to feature and create a split line of the text on the surface of the radar.
• lastly, apply fillets to the model and save the file as "Radar".

Hull:

The hull of a ship is the most notable structural entity of the ship. To define the hull, it can be said that it is the watertight enclosure of the ship, which protects the cargo, machinery, and accommodation spaces of the ship from weather, flooding, and structural damage. So, it is the main body of the ship which has its own crucial functions to execute to protect the ship therefore, this part must be designed with considering all the technical aspects also looking at the aesthetic looks of the ship.

Features use to create Hull:

• Surface loft
• Surface trim
• Surface extrude
• Surface fill
• Shell
• Boss-Extrude
• Cut-Extrude
• Chamfer
• Fillet
• Sweep
• Revolve
• Dome
• Helix spiral
• Surface offset
• Mirror
• Surface knit

Projected Curve: This feature is used to create complex curves by combining two sketches drawn on two different planes. This feature is very helpful for creating complex geometry curve in our hull model we have used this feature many times as creation of hull requires complex curve to created as a surface and then convert it into solid geometry.

Surface Loft: This feature is used to create a lofted surface between two or more sketch profiles or curves generated. In our Hull model, we have used this feature to create a lofted surface by selecting two curves as shown below.

Surface Trim: This feature is used to trim the intersecting surfaces thereby removing the unwanted surfaces.

Surface extrude: This is used to create an extruded surface from a previously drawn sketch.

Surface Fill: This feature is used to create a surface patch within a boundary defined by existing model surfaces, sketches, curves, etc.

Shell: Removes material from the solid body thereby producing a thin-wall feature this is a very helpful feature to create hollow thin-walled structures.

Cut-Extrude: This feature is used to remove unwanted material from our solid body to give us the required part or model.

Boss Extrude: Extrudes the sketch profile into one or both directions thereby producing a solid body.

Fillet: This feature is used to create round internal or external faces by selecting edges, faces of a solid body, or surfaces.

Chamfer: Creates a chamfer or bevel along a selected edge or chain of edges, vertex.

Surface Knit: This feature is used to joined selected surfaces together to form a single surface by filling up the gaps between the two surfaces.

It is very important to knit the surfaces so, as to form a solid body from the surface body.

Sweep: This feature is used to sweep a sketch profile along an open or closed path to create a solid part.

Helix Spiral: This feature adds a helix curve or spiral from a sketch circle.

Revolve: This feature is used to sweep a sketch entity, profile along with an axis or centerline at a 360-degree angle to give a solid part or model.

Procedure to be followed to model Hull:

• First open the blueprint setup file in Solidworks, save as this open file with a new name as hull
• Then select the midplane and start a sketch on the midplane turn-on the show option for the side view blueprint and draw a spline by taking the edge of the hull shown in the blueprint.
• Once completed close the sketch, select the top plane as the sketch reference plane and draw a sketch by using spline by taking the reference of the edge as shown in the blueprint of the hull in top view and closed the sketch.
• Click on the projected curve feature in the features tab and select the two sketches to generate the curve.
• Next, start a new sketch by selecting the midplane and draw a spline on the edge of the hull shown in the side view blueprint try to match the spline with the blueprint edge, and then closed the sketch.
• Draw another sketch on the bottom plane by using a spline and closed the sketch.
• Select these two sketches and click on the projected curve option in the features tab to generate a curve.

• Closed these projected curves by drawing a line joining the endpoints of curves by selecting the appropriate planes to sketch.
• Completed with this select the lofted surface option to create a surface between these two curves and click ok.
• Create another surface loft by drawing two more sketches one on the midplane and another on the backplane.
• Then trim the unwanted surface by sketching the midplane.

• Use the surface fill option to create an upper surface of the hull part.
• Use again the surface fill option to completely create a closed surface body and then select the surface knit option to knit the surfaces and click on try to form solid option.
• A complete solid body will be created then select the shell option to create a thin wall body.
• Then complete the rest of the hull part as shown in the blueprint and at last used the mirror option to create the mirror of the half structure of the hull and save the file.

Superstructure:

It is a complex structure that is constructed on an existing part of the ship that mostly comes in the upward direction from the deck surface. In our model we have created a luxurious superstructure on the deck surface it is the control room of the ship we can control the ship from the superstructure. Its design is done in such a way that it does not hinder the speed of the ship or the mobility of the ship.

Assembly of Sunseeker Predator Yacht:

After all, the individual parts of the Yacht are created the next step is to assemble them to prepare our final complete yacht.

Assembly is the systematic arrangement of all parts with required relations to form a complete product or model we can also create a mechanism with the help of assembly for that purpose we need to create a new assembly in Solidworks software.

Procedure to be followed for assembly of Yacht:

• The first step is to open new assembly in Solidworks software then select add components/parts option from the Features menu
• Open the first part i.e the Hull now we need to give relation to this open part there are several relations available such as fix, float, tangent, perpendicular, etc. from that options select the fixed one because the Hull is the first component on which all other parts are to be assembled.
• Then start adding other parts to the assembly and apply required mates to the parts to make it fully defined and prepare our Yacht assembly.

Features use for assembly of Yacht:

• Mates

Mates :

By using this feature in the assembly menu we can provide a relationship between the different parts of our assembly the main purpose of applying mates is to restrict the motion of our part i.e the degree of freedom. This is only possible through applying mates there are several types of mates which we can provide they are as follow:

• Tangent
• Perpendicular
• Concentric
• Horizontal
• Vertical
• coincident
• Parallel

By providing this mate we can fully define our assembly there is an advanced mate option by using which we can provide restricted motion to different parts of our assembly, we can provide angular motion to the parts by using this option and it is also helpful to create a certain type of mechanism.

Rendering:

• Rendering is the process of creating realistic images of the created assembly in different environments by providing different appearances to the existing model to showcase our design
• By use of this feature, we can transform our model into a real object to create the illusion of how our actual object will look like and it helps us to get a more clear idea about the concept of our new product and its appearance.
• It can be done by using two different software in Solidworks
• Photoview 360
• Solidworks Visualize

Photoview 360:

This is provided in Solidworks software as an Add-in option it is a visualization and rendering solution providing different environments and appearances options for our model and then render it into that environment to create a photo-realistic image of the model.

Solidworks Visualize:

Solidwork Visualize is completely separate software for transforming our 3D cad files into realistic high-quality images with an en-number of tools. We can create from images to animations, interactive web content, and immersive Virtual Reality with ease and in a faster way.
