The main objective of this course module is to learn the basics of part modeling and also exploring most of the tools that are used in designing using solid works.

The following steps were undertaking while designing the American Chopper:

1.Design of the individual components

2.Assembly of the American Chopper

3.Application of decals,setting up the scene,lights and cameras

4.Final rendering of the American Chopper

METHODOLOGY

The American Chopper is made up of following parts:

1.Transmission belt

2.Kick stand

3.Chain

4.Rear fender

5.Rear wheel

6.Pedal

7.Front fender

8.Front wheel

9.Oil tank

10.Front work

11.Chasis

12.Engine

13Fuel tank

1.TRANSMISSION BELT

It is used to transmit the power between the two shafts in the engine.

Feartures used :

• Extrude Boss/Base
• Fillet

The profile of the transmisson belt is created as per the dimension in the front plane,the belt is given a thickness of 3.5mm.once the sketch is complete the belt is extruded.The square edges are given fillet.The transmission belt is made out matte rubber.

2.KICK STAND

Kick stand is a supporting structure provided to a bicycle or motorcycle to help it stand in a vertical position when stationary.

Features used:

• Lofted Boss/Base,
• Dome
• Extruded cut
• Extruded Boss/Base
• Fillet

Mainly loft feature is used to create the Kick stand.Two ellipses are created on the right plane,one at the top end and one at the bottom end of the kick stand. A path is sketched on the front plane which joins the center points of the two ellipses created before using pierce relation between the center of the ellipses and the path. using loft the body of the kick stand is created. Elliptical dome feature is used to create the rounded end of the kick stand. A slot with an extruded boss is created boss is created at the top end of the stand using which it is connected to the chassis. At last fillets are provided to the sharp edges of the stand. Chrome plate appearance is applied to the kick stand.

3.CHAIN

• Combine

A main profile of the chain is created using three point arc and tangent relations between the arcs using the given dimensions. create two throw away sketches which are used to create the inside and outside the links of the chain. The plates of the chain. The plates of the chain links are extruded using the throw away sketches and the connecting pins are craeted using the same sketch. Only one side of the plates of the chain links are created. The created chain links are pins are then populated on the main sketch using the linear pattern and circular pattern features. All the chain link plates are then mirrored on the front plain. All the components of the chain are combined as a single part using combine feature. Cfrome steel appearance is appplied to the chain.

A spider web design of the rim is created on the front plane and is extruded using mid plane extrude feature and this spider web is circular patterned to required numbers and the Rim is completed. The spider web spokes and the rim are combined to form a single solid body.

For Rotor: Sketch on the front plane and extrude it to the required dimensions. Create the necessary holes using circular pattern.

For Caliper: Create a profile using lines and circles and remove the unwanted sketch and midplane extrude the caliper profile. Provide necessary fillets and chamfers to complete the caliper.

For Sprocket: sketch a circle and extrude it to the required thickness. Apply chamfer to the outer edges and create a tooth profile on the extrude and cut it. Apply fillets to the tooth edges and create the sprocket using circular pattern feature and required number of teeth.

For Tyre:A sketch is created by converting entities of the Rim and the Tyre is revolve extruded. Later profiles are created on the surface of the Tyre to give the grips to the tyres.

seperate apperance are applied to each part of the wheel.

Now mirror the created part of the tank and knit the entire surface together. Now apply appropriate materials to the gas tank and the seat.

ASSEMBLY OF THE AMERICAN CHOPPER

All the deisgned components are taken into the assembly section in solid works and using different mating features such as concentric, coincident, parallel,etc., the entire assembly of the

American Chopper is created .After assembly the decals are applied to the chopper.

Once the application of the decals is finished the assembled motorcycle is taken into solid works Visualize or using photo-view 360.Here various aspects such as camera, external lightings,

background scenes, etc.are taken into consideration before the creation of the final rendering. The final rendered images of the American chopper are derived.

Rendered American Chopper

CONCLUSION:

• The parts of the chopper or sketched and modelled in the solid works.
• The parts are inserted into the assembly environment and by applying the mates the whole American Chopper is assembled.
