Photo Realistic Rendering of American Chopper

MODELLING AMERICAN CHOPPER USING SOLIDWORKS

OBJECTIVE:

• To model various parts of American Chopper in Solidworks PART.
• Assemble the parts of American Chopper in Solidworks ASSEMBLY.
• Photorealistic rendering using Solidworks PHOTOVIEW 360 and Solidworks VISUALIZE.

In this project we will be understanding basic knowledge on Part modelling , Assembly and Photorealistic rendering from intermediate to some advanced level, all in Solidworks. It will also serve us, as a guidance to interpret with solidworks in a efficient and practical manner to achieve our desired objectives and results, and also an Interesting project to start with for a Beginner in Solidworks.

1.Transmission belt: It is used to transmit power from Engine to Gear Box.

Features used:

• sketch

• sketch:It is used to create two dimensional images on a plane.The images are drawn with the help of varoius sketching tools like Line, Circle, Spline, Arc, polygon etc.

• Offset:It is used to offset entities by specifying distance either from one direction or in both directions.

• Extrude:Helps to convert 2D sketch in to a 3D solid.

• Fillet:It helps to round the sharp edges of solid or surface faces to the specified radius.

• Appearances:It gives color and texture to the part without affecting physical properties.

Procedures to create the model:

• Open solidworks.clik New, select Part and then click ok.
• Select front plane, click on sketch tool.
• Draw the 2D sketch with proper dimensions and relations to fully define it (sketch turns black).
• Exit the sektch, select extrude boss/base from Features, add dimensions to create solid model.

ASSEMBLY OF AMERICAN CHOPPER:

1.In this section we will be assembling all the parts created in solidwork with proper mate in solidworks Assembly.

Procedure to create an assembly file in solidworks

• Open solidworks.
• Click new > select assebmly > click ok.
• Insert all the parts by clicking .
• After the assembly is complete, save it.

Features used in assembly:

• Mate:Mate has numerous function to constrain the parts assembled to work as needed.The types of mate include standard mates, advanced mates, mechanical mates.

PHOTOREALISTIC RENDERING OF AMERICAN CHOPPER:

Rendering is used to create an photorealistic image of a part, assembly, or 2D sketch with appearences, lighting, scene, decals etc.In solidworks, rendering can be done with

• Photoview 360
• Solidworks visualize

Rendered images:

CONCLUSION:

• The above parts, assembly and rendering are done using solidworks.
• This project helps us to learn the essential tools and techniques required, which can be effectively used for our further projects in solidworks.
