Photo Realistic Rendering
THE AMERICAN CHOPPER
- OBJECTIVE:- Using Solidworks, The objective of this project is to create a model of an American Chopper.
The primary objective was Part Modeling after that Assemble parts under the assembly environment and lastly
Photorealistic Rendering for better visualization.
- INTRODUCTION:- A Chopper is atype of custom motorcycle which emerged in California in the late 1950s. The Chopper is perhaps the most extreme of all custom styles, often using radically modified steering angles and lengthened forks for a stretched-out appearance. They can be built from an original motorcycle which is modified or built from scratch. Some of the characteristic features of chopper are long front ends with extended forks often coupled with an increased rake angle, hardtail frames, very tall Ape Hanger or very short Drag handlebars, lengthened or stretched frames, and larger than stock front wheels.
- DESIGN METHODOLOGY:-
- PART MODELLING
1. TRANSMISSION BELT:-
A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel.

2. KICK STAND:-The kickstand is a swiveling metal bar for holding a bicycle, motorcycle, or another two-wheeled vehicle upright when it is not being ridden and is used for the safety of the vehicle. It is pivoted to the axle in such a way that it can be kicked down below the frame.

9. FRONT FORK:- The front fork is a suspension component for either bicycle fork or motorcycle fork. The forks can be most easily understood as simply large hydraulic shock absorbers with internal coil springs. They allow the front wheel to react to imperfections in the road while isolating the rest of the motorcycle from that motion.

12. GAS TANK:- The gas tank acts as a reservoir to meet the fuel requirements of the chopper.
- Storage of fuel: the system must contain a given quantity of fuel and must avoid leakage and limit evaporative emissions.
- Filling: the fuel tank must be filled in a secure way, without sparks.
- Provide a method for determining the level of fuel in the tank, gauging (the remaining quantity of fuel in the tank must be measured or evaluated).
- Venting (if over-pressure is not allowed, the fuel vapors must be managed through valves).
- Feeding of the engine (through a pump).
- Anticipate potentials for damage and provide safe survival potential.

- ASSEMBLY
Assembly is done in the assembly environment by inserting all the modeled parts of the chopper using insert part option.
Parts of the chopper are fixed in the assembly environment by giving possible mate conditions or by fixing the planes.
You can build complex assemblies consisting of many components, which can be parts or other assemblies, called subassemblies. For most operations, the behavior of components is the same for both types.
Adding a component to an assembly creates a link between the assembly and the component. When SOLIDWORKS opens the assembly, it finds the component file to show it in the assembly. Changes in the component are automatically reflected in the assembly.
MATES
Mates create geometric relationships between assembly components. As you add mates, you define the allowable directions of linear or rotational motion of the components. You can move a component within its degrees of freedom, visualizing the assembly's behavior.
TYPES OF MATES
The various types of mates available in Solidworks are:-
- Standard Mates - Angles, Coincident, Concentric, Distance, Lock Parallel, Perpendicular, Tangent mates.
- Advanced Mates - Limit, Linear/Linear coupler, Path, Symmetry, Width mates.
- Mechanical Mates - Cam-follower, Gear, Hinge, Rack and Pinion, Screw, and Universal joint mates.
- Images of the assembly: Following are the images of the chopper assembly in different views,
- PHOTOREALISTIC RENDERING OF CHOPPER
Rendering is the process of creating realistic images of the Photorealistic model with the environment. Rendering has been done in two ways in solidworks. The following are the two ways:-
1. Photoview 360
2. Solidworks Visualize
- PHOTOREALISTIC RENDERED IMAGES OF AMERICAN CHOPPER
CONCLUSION
All the parts of the American chopper were modelled and the assembly was created using Solidworks and the Photorealistic renders of the chopper were created using Photoview 360 only.
NOTE :- 'SOLIDWORKS VISUALIZE SOFTWARE IS NOT INSTALLED IN THE SYSTEM DUE TO SOME ERROR AND THE SAME IS INFORMED DURING ONE ON ONE SESSION. WORK IS DONE ACCORDING TO TECHNICAL TEAM GUIDANCE & PERMISSION'.
