Ultimate SOLIDWORKS Course

Title:

To model and assemble of American chopper using and solid and surface modeling in solid works.

Objective:

Drafting and designing the American chopper bike using solid works.

 Introduction:

The design of the American chopper bike involves creating the individual parts initially and assembling them with proper connections and alignment.

SolidWorks: Solid works is a solid modeling CAD computer program that runs primarily on windows.

American chopper: A chopper is a type of custom motorcycle. The chopper perhaps the most extreme of all custom styles, often using radically modified steering angles and lengthened forks for a stretched-out appearance. Some features of the 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.

Choppers were built in America are tended to be based on Harley-Davidson motorcycles.

It is not about performance-oriented modifications, choppers are more about achieving a certain look. The main purpose of this project is to create an aesthetic model of a chopper using Solid works.

Chain:

The Chain drive is used to transfer power from one place to another, similar to a transmission belt. A chain drive is a positive drive motion since there is no slippage between the belt and gear. Drives are made of metal, followed by plastic and rubber. They are very efficient in power transmission. Lubrication is important since the drives wear out quickly without proper lubrication. Chain drives suffer from speed controlling since the drives are made from metal, they have significant self-weight which gives rise to inertia during rotation. Hence special care has to be taken to avoid such situations, which in turn will reduce the chances of vibration and increase the life of the chain drive. In most cases, either the shafts accelerated and deaccelerated accordingly, or the sprocket is speed controlled. Sometimes Chains are often narrower than belts, and this can make it easier to shift them to larger or smaller gears by varying the gear ratio. Multi-speed bicycles with derailleurs make use of this. The more positive meshing of a chain makes it easier to build gears so they can increase or shrink in diameter, by altering the gear ratio.

Steps for modeling Chain:

1. Start sketching on the midplane by drawing two circles and connecting them by line. Then remove the unwanted lines using the Trim Entities tool.
2. After that in the same plane draw the two-chain links and save them as blocks.

Let us seem to be at each of them and how it influences mud retention. 

Draft- when a footpeg has a fantastic draft it virtually potential that the lower opening is better than the one at the top. This implies that we are probable to experience minimal mud traps.

Thickness- normal foot pegs normally make use of extra manufacture material, this in most instances creates deeper cavities that lure a lot of mud. On the different hand, super-thin foot pegs best in seasoned circuit units. They are most desired here they are magnificent skinny and they, therefore, don’t supply any room for mud to be trapped.

Nooks and crannies- simplified difficult and crossbeams footpegs do not entice any mud as antagonistic to their different counterparts

5. Then another plane is created concerning the Midplane and a sketch is drawn.
6. Again, make another plane and draw a sketch. Sketch another plane that was created previously and using the two sketches make a projected curve.
7. Sketch on the plane that was created previously and using the Surface Loft tool make a surface loft.
8. Now make another plane concerning the front plane and draw a sketch. Sketch on the Bottom plane and these two sketches are used to create a projected curve.
9. For creating a boundary surface draw two sketches on the midplane and then using the Surface Boundary tool to make it.
10. By using the mirror tool make a mirrored version of the part over the midplane.
11. By using the surface knit option knit all the surfaces.
12. Then for making the seat sketch the Bottom plane and the split line option are used to combine with the gas tank body.
13. By using the surface extrude seat is generated.
14. Later some fillets are given to the seats.
15. Again, the boundary surface is created for the seat.
16. Now a surface loft is made at the bottom of the gas tank using the loft option from the surface window.
17. By using the surface knit option knit all the surfaces.
18. After that, some fillets are applied.
19. Now draw a sketch on the midplane as well as on the plane that was created concerning the front plane and using the cut sweep option cut the part.
20. Fillets are applied and the whole part is made into a shell.
21. After that, appearances are given to the part and the seat separately.

Tools used for modeling Gas Tank:

• 2d sketch
• spline
• surface sweep
• surface trim
• surface boundary
• surface loft
• curve
• mirror
• surface knit
• surface extrudes

ASSEMBLY OF CHOPPER

Assembly:

All the above individual parts are assembled with appropriate joint features to form the final output of the American chopper bike as shown below using the features

1. inserts parts
2. mates

1.Insert part is used for bringing in the part models which we designed individually into the assembly so that the part can be assembled and rendered.

2.mates are used to create relations in between the part models so that they act as a combined part and work as desired and lock the movement in the desired position. And to fully define the part model.

Steps for assembling the part models of the chopper:

• All the parts are added that are created in the SolidWorks software and keep them open and then start assembling by creating a new assembly file.
• By using the insert component option chassis is added to the window and then make it coincident mate using the mate option for the midplane and the front plane of the assembly.
• After that add the engine and make its bottom stand coincident with the flat bottom surface of the chassis. Then make a distance relationship between the front surface of the bottom stand and the front surface of the holding part of the chassis.
• Now add the pedal to the window and make its two cylinders concentric with the holes given on the chassis and make its one side coincident with the chassis. After that, the pedal is mirrored on the other side of the chassis.
• Now kickstand is added to the window and make its inner surface coincident with the outer surface of the part that is on the chassis.
• Now give a concentric mate to the kickstand and the chassis.
• To limit the movement of the kickstand a limit angle is given to the kickstand concerning the chassis.
• Then the transmission belt is added and a width mate is given to it concerning the engine and also a concentric mate is given to it.
• After that, an angle is given to the transmission so that it stays fixed.
• Now oil tank is added and coincident relation between its face and the face of the engine near the seat is given. Again, a coincident relation is given to the edge of the tank and the surface of the engine.
• Then another coincident relation is given concerning the midplane of the tank and the chassis.
• The rear wheel is added and given a concentric relation between the chassis and the wheel. Now a coincident relation is also given between the midplanes of the chassis and the wheel.
• For fixing the position parallel relation is given between the front plane and the side of the chassis just after the wheel.
• The rear fender is added and made concentric with the disc of the rear wheel. And a coincident relation is added to the midplanes of the rear fender and the chassis.
• After that, a parallel relation is given to the front plane of the rear fender and the side of the chassis.
• The chain is added and given a width relation between the one side of the chain-link and one side of the sprocket.
• Now the other side of the chain is fixed using the parallel relation between them.
• Then the gas tank is added and is given a distance relation between its front plane and the front plane of the chassis.
• After that, some coincident relations are given to align with the chassis of the chopper.
• The front fork is added and given a concentric relation between its axis and the chassis to fix it.
• After that, a width relation is given to the two surfaces of the fork and the chassis.
• The angle of tilt is limited using the angle relation between the plane of the fork and the chassis to prevent over-rotating.
• After that, a parallel relation is given to the chassis and the fork so that whenever we want, we can position it in a straight position.
• The front wheel is added and given a concentric relation between the fork and the front wheel.
• The front wheel is given a coincident relation between the planes of the wheel and the fork.
• The front fender is added and given a coincident relation between various planes of the fender and the fork to position it.
• Rebuild the chopper to update any change and save the file.

Rendering:

get the realistic viewing effect using photoview360 or SOLIDWORKS Visualize. where we can adjust the viewing direction using the camera option and place the model in a realistic environment and render the image to get the real-life viewing angles and shadows, etc...

 

1. Environment
2. Decals
3. Lights and Cameras.
4. Snapshots.
5. Plates
6. Textures
7. Render preview window.
8. Final Render.

Environment: In this, we use HDR images to generate rendering it is a type of real environment in which shadows of the environment are projected onto the model. To create a real-life image.

Decals: It is used to create labels or logos on the part to make it look like a laser-cut logo.

Lights and Cameras: these are used to capture the view and Lights are used to increase lighting and to create artificial sunlight.

Render preview window: It is used to view the rendered image before doing the final rendering as final rendering takes so much time.

Final Rendering: when we think of the rendering, the preview is ok and giving a good result we use the final render to generate a high-quality image.
