American Chopper Modelling Using SolidWorks

Objective:-

• To create a model of different part of Chopper.
• Assembly of different part of model for Chopper.
• Create a photorealistic model and render the model of the Chopper using Solidworks Photoview 360.

What is part modelling ?

Part Modelling is feature in which I create solid body and see the part that how to looking in reality, like as realise the vertuility. It uses different purpose. With the help of this I create many parts and assemble them and check it. If it is not correctly then I can change in part. And get a final part.

Part which is created for American Chopper :

The following part of the chopper is modelled by Solidworks and assembled them.

1. Transmission Belt
2. Kickstand
3. Front Fender
4. Rear fender
5. Oil Tank
6. Chain
7. Pedal
8. Front Wheel
9. Rear Wheel
10. Front Fork
11. Chassis
12. Engine
13. Gas Tank

Now let us see the every part in detail.

1. Transmission Belt :- In the Chopper transmission belt is used to transmit the power from engine to gearbox.

   Feature is used to create the transmission belt.

   • Sketch
   • Offset
   • Extrude
   • Fillet
   • Appearance

   Sketch- Sketch is a 2D drawing representation respect to the plane in solidworks. It is a basic drawing. I draw a sketch with the help of line, arc, rectangle, circle, spline etc.

   Offset- Offset is a feature with the help of this I draw entities with offset distance from reference which I select. I can select a many reference like line, arc, circle etc in one time.

   Extrude- Extrude is a feature in which I convert 3D solid body from 2D sketch.

   Fillet- Fillet is used to where the edge is on the body (external or internal). With the help of this I change the edge into circular edge.

   Procedure followed to create the model of transmission belt.

   • First of all I opened the solidworks software. Then click the new part to create the model.
   • Before draw the sketch I changed the default plane name as
   • Front plane – Front Plane Transmission Belt
   • Top Plane – Top Plane Transmission Belt
   • Right Plane – Right Plane Transmission Belt
   • Then Front Plane is selected to sketch.
   • I draw a 2D sketch with given dimension and relation with fully defined. And create a duplicate sketch from some distance with the help of offset entities.
   • After it I changed the 2D sketch to 3D body.
   • Then I gave the fillet as required dimension. After it the model of transmission belt is ready.
   • And then I saved with part name as Transmission Belt.
2. Kick-stand :- Kickstand is used when the bike is on rest (stand) position. With the help of this I can stand the bike anywhere on plane surface.

   Feature is used to create the Kickstand.

   • Sketch

Surface Trim – By this tool we trim (cut) the surface where I want.

Surface Knit - Surface Knit is used to knit the 2 free edge of the surface together. It also reduce the gap between two surface.

Assembly of Chopper Model :-

First of all I inserted the chassis part in assembly feature in environment. After that I fixed the chassis. Then I insert the every part one by one and assembled the part with chassis by mate tool.

Feature is used to assemble the Chopper Model.

• Insert
• Mates

Where as ,

Insert - Insert is a option by which we insert the part of model.

Mates - Mates is a geometrical relation combination. With the help of this we mates the part as possible relation. We can move a component within degrees of freedom.

Photo Realistic Rendering :-

• Rendering is the process of creating realistic image of the Photorealistic model with the environment.
• Rendering has been done in two ways in solidworks.
• Photoview 360
• Solidworks visualize
• In the photorealistic model some of the mate condition and position are changed to render realistic model.
• Then realistic model is rendered into realistic image with different views.

Here are some Rendered images-

Conclusion :

• The parts of the Chopper are modelled using most of the Solidworks modelling tool in solidworks.
• The parts are inserted into assembly environment and Chopper is assembled using assembly module of solidworks.
• The realistic image was rendered with the use of Photoview 360 & Solidworks Visualize.
