Description

1. Transmission

Features: Boss Extrude/ Base and fillet

This part is created by sketching into Front plane. The profile is created with a line, 3 point arc followed by Extrude. Extrude is a feature which convert the 2D sketch into 3D.Apply fillet for the sides. Once the design part is completed it can be saved with a file name.

2. Kick Stand

Features: Lofted Boss/Base, Dome, Extrude cut, Boss Extrude/ Base and fillet

This Part is created by sketching in Right Plane. The profile is created by two ellipse followed by a patch which joins the center of two ellipse. The path can be joined using pierce relation to center or directly joining on the center points. Loft is the feature which is used for creating the body of stand. Dome feature is used to create the rounded end. Extrude cut feature is the feature used create a cut on top end which joins the chassis. Once design part is completed it can be saved with file name.

3. Chain

Features: Boss Extrude/ Base, fillet, Circular pattern, Mirror, Combine

This part is created with 3 point arc and line with tangency. In this two inner and outer links of the chain is been created with circles and lines. The link is extruded and they are to be saved as nodes. Those links are to be linked with actual chain sketch and features like curve driven pattern and liner pattern to be used at the appropriate sections. Once all the links are set the final chain link to be manually drawn to confirm that it gets perfect with the other links. The inner, outer chain links and the pins can be stored in folder to avoid confusion. Once all are completed the appearance has to be set to chrome steel.

4. Rear Fender

Features: Boss Extrude/ Base, fillet, Shell

This part is created by sketching in front plane. It is created by using a 3 point arc and feature like offset is used, the reference line from the origin has been created in order to use the feature revolve in which the face is created additional feature like fillet is used to convert sharp edges to smooth one. The appearance for the part can be created using render tool and save the part with file name

5. Rear Wheel

Features: Boss Extrude/ Base, Revolve Boss/Base, Extrude cut, Revolve cut, Circular pattern, Mirror, Combine, Chamber and fillet

In this part we are going to create four integral parts such as

• Rotor
• Caliper
• Sprocket
• Tire

The part Rim is created by sketching in front plane by revolving with the imaginary/ reference axis then the part is extruded. On the Extruded part a sketch is created like a spider web which will indicate the rims, the same sketch is extruded from mid plane using feature Extrude- MidPlane. The entire web feature is constructed using spline and three point arc. The unnecessary regions are trimmed using power trim and the same is mirrored with the reference.

Rotor is created by sketch in front plane and on the face of rotor circles are created and made an extrude cut. Then the circles are expanded using circular pattern.

Caliper is created from the reference of rotor by using lines and arc joining. The part is then Extruded using Midplane extrude feature. The fillet Chambers are used to make the sharp surfaces as smooth.

Sprocket is created using a circle. On the circle a sketch will be performed in order to bring teeth for the sprocket, then the sketch will be made with an extrude cut up to next feature and the cut region will be expanded using circular pattern along with the applied fillets

Tire is created by using the feature of Convert Entities of the rim. Using that as reference the tire is revolved. On revolving the tire will have a good face, on that face geometry will be created using midpoint rectangle. Those sketches will be aligned and given dimensions and will be cut with extrude cut feature for getting the pattern of grips. Once those are done it will be expanded using Circular Pattern feature.

Finally all body will be given an appearance with render tool and will be saving with file name

6. Front Tire

Another sketch is created on the tank for seat and extruded. The entire body is mirrored using reference plane and knit feature is used to knit the surface together. Appropriate appearance is used for the part from render tools

Assembly of Chopper

To assemble we need to open assembly section and insert all part designs. Keeping the Chassis as a reference and each part needed to be assembled. The parts can be rotated to desire one using the axis. The assembly will be done using parallel, concentric and coincident relations. The decals can be inserted using the render tool.

Assembled Chopper

Creating a Final Render Using SolidWork Visualizer

The assembly is taken into Solidworks visulaizer and its backgroud are changed by inserting a background and the brightness is adjusted and it is allowed for final render.

Conclusion

Thus the project Design, Assembly and Rendering of American Chopper using Solidworks has been created and completed successfully.
