MODELING OF AMERICAN CHOPPER ON SOLIDWORKS

OBJECTIVE

To design an American chopper using Solidworks Solidworks
To learn basic commands of Solidworks
To create all parts of American chopper and assemble them
To do rendering
Getting realistic with the help of photo view 360

INTRODUCTION

During this course, I learned how to design an American chopper assembly using Solidworks software. Initially, I learned about commands of Solidworks and started using them while designing American chopper. After completing the design of all parts I have done assembly of the chopper. After assembly, I have done rendering using photo view 360.

The following parts are designed during this course

1) Chasis

2) Engine with exhaust system

3) Front-wheel

4) Rear Wheel

5) Front fork

6) Front and rear fender

7) Oil tank

8) Chain

9) transmission belt

10) Kickstand

11) foot pedal

Design approach

STEP 1

Get to know about the Commands and Features of Solidworks.

Step 2

Started Designing each and every part of American chopper

Completed design of every part.

Step 3

Assembled all parts to get final Bike

Step 4

Rendering was done after assembly

Photo View 360 is used to get a realistic view

Description of features and commands used while designing parts

Extrude Boss: It is used to convert a 2D sketch into a Solid body. It can create a completely solid body of any shape with closed entities. In this feature, we can select the dimensions also.

Fillet: To avoid sharpness at the edges this feature is used. To give Roundness to the sharp edges we add fillets. Fillets not only to hides the sharpness of the solid body but also gives a good appearance to the body.

Revolve boss feature: This feature works around an axis, by selecting the axis of a sketch adds a round material by revolving around that axis. if there is no axis we can select an edge of a sketch and it gives us appropriate geometry.

Shell: This command gives some Idea about the inside appearance of a part. To make the body hollow this tool is used.

Linear patterns: This tool helps to create a single sketch that can be used multiple times. This feature is spaced uniformly along one or 2 linear paths.

Mirror: It creates a copy of solid parts. Apply feature to one or more multibody parts by selecting geometry patterns and using feature scope to choose which body should include the feature.

Projected Curve: This command is used to project a sketch into a 3D curve. By using this command we can create multiple projected curves from a single sketch. It does not create a curve of intersecting curves

Knit Surfaces: This is used to combine 2 or more faces and surfaces into one.

Mate: It is used to connect 2 components. Mate creates geometric relation between assembly and component. When we use the mate tool it defines the allowable motion of the component within its degree of freedom. The following are the mate features

1) Coincident mate 2) Concentric mate 3) Tangent 4) Angular mate

Transmission Belt :

The transmission belt is located at the round surfaces of the pulley to transmit the power with the help of pulleys.

The features used while creating the Transmission belt are as follows

Front Wheel

Front-wheel is located at the front portion of the bike. Front-wheel experiences greater force during breaking so, its diameter is more than the rear wheel.

Assembly of the chopper :

After designing all parts, the parts are assembled to create a complete Bike. During the assembly, the Mate feature is mostly used to connect the components.Few parts are modified to make it perfect according to requirements.

Decals :

In this portion, I attached stickers to the bike. Stickers are placed on the Rear fender, oil tank, and Gas tank. This gives a nice appearance to the chopper.
