Solid Modelling of American Chopper

American Chopper

Introduction:

Solid modelling (or modelling) is a consistent set of principles for mathematical and computer modelling of three-dimensional solids. Solid modelling is distinguished from related areas of geometric modelling and computer graphics by its emphasis on physical fidelity.

Part Modelling:

• Part Modelling you can create a part from a conceptual sketch through solid feature-based modelling, as well as build and modify parts through direct and intuitive graphical manipulation.

Objective:

• The objective of this project is to solid model different parts of the Chopper using Solidworks and to assemble modelled parts.
• To create a Photorealistic model and Render the model of chopper using Solidworks Photoview 360 or Solidworks visualize.

Parts to be modelled for chopper:

1. Transmission Belt
2. Kick stand
3. Front Fender
4. Rear Fender
5. Oil Tank
6. Chain
7. Pedal
8. Front Wheel
9. Rear Wheel
10. Front Fork
11. Chassis
12. Engine

• Oil Tank:

The Oil tank is one the part of the Chopper. Oil tank is used to store the oil required to run the Engine. Oil tank is the Hollow one. The thickness of the oil tank is given as 3mm in our chopper.

Features used to create Oil Tank

• Sketch
• Boss Extrude
• Combine
• Fillet
• Shell
• Appearances

• Chain:

Chain is a type of transmission system that is used to transmit a power from the Engine to the Rear Wheel. Chain is made of steel. The Sprocket is used to transmit the power to the chain. The sprocket is connected with the Shaft with the help of a key.

Features used to create Chain

• Sketch
• Trim
• Fillet
• Blocks
• Extrude
• Patterns
• Appearances

Blocks

You can make, save, edit, and insert blocks for drawing items and sketch entities that you use often, such as standard notes, title blocks, label positions, and so on. You can attach blocks to geometry or to drawing views, and you can insert them into sheet formats.

To make blocks:

1. Create a sketch.
2. Click Make Block. (Blocks toolbar) or Tools > Block > Make....
3. Select the sketch entities you want to make as a block for Block Entities.
4. Click.
5. Repeat steps 2-4 for each of the remaining sketch entities.
6. With the sketch in edit mode, add the necessary relations.
7. Save the part.

• Pedal:

Pedal is the external part attached to the chassis. The pedal is used to place the leg on top of that. To give comfort to the rider pedal is used.

Features used to create Pedal

• Sketch
• Extrude
• Fillet
• Linear pattern
• Dome
• Chamfer
• Appearances

• Front Wheel:

A wheel is a circular block made of the Steel/Alloy material. On the top of the wheel the tyre is covered. The tyre is made of Rubber and it has thin wires within it.

Features used to create Front Wheel

• Sketch
• Revolve
• Trim
• Fillet Entities
• Boss/Base Extrude
• Revolve Cut
• Linear pattern
• Chamfer
• Fillet Features
• Cut Extrude
• Circular Pattern
• Appearances

• Rear Wheel:

A circular object that revolves on an axle and is fixed below a vehicle or other object to enable it to move easily over the ground. The disc and sprocket are attached with a rear wheel. The chain is connected between the Engine and the Rear Wheel. Chain is a positive drive. Compared to the belt it will be more efficient and losses in the chain will be less comparatively.

Features used to create Rear Wheel

• Sketch
• Revolve
• Trim
• Fillet Entities
• Boss/Base Extrude
• Planes
• Revolve Cut
• Linear pattern
• Chamfer
• Fillet Features
• Cut Extrude
• Circular Pattern
• Appearances

• Front Fork:

Most motorcycles today use telescopic forks for the front suspension. 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.

Features used to create Front Fork

• Sketch
• Extrude
• Trim
• Revolve
• Split
• Plane
• Convert entities
• Move/copy Body
• Dome
• Mirror
• Combine
• Curve (Project Curve)
• Sweep
• Appearance

• Chassis:

A chassis or frame forms its skeleton. All the components of a motorcycle, like the suspension, wheels, fuel tank, seats, handlebars etc, are attached to this base structure which lends a motorcycle its strength and ability to handle well.

Features used to create Chassis

• Sketch
• Offset
• Convert entities
• Project Curve
• Trim
• Plane
• Sweep
• Split
• Revolve
• Cut Extrude
• Fillet
• Combine
• Appearance

• Engine:

• Engine is the prime mover for the Bike. The engine converts a Chemical energy into the Heat energy and then the heat energy is converted into mechanical work.
• The mechanical work in the engine is rotational motion. This rotation is converted to the wheel with the use of the chain and sprocket through the gearbox and clutch.

Features used to create Engine

• Sketch
• Convert entities
• Trim
• Revolve
• Boss extrude
• Cut extrude
• Offset
• Dome
• Fillet
• Project curve
• Composite curve
• Sweep
• Mirror
• Circular Pattern
• Split

• Gas Tank:

Gas tanks are used to store the gas. To give the gas to the engine whenever it’s required.

Features used to create Gas Tank

• Sketch
• Trim
• Project curve
• Convert entities
• Sweep Surface
• Loft Surface
• Fill surface
• Surface trim
• Surface knit
• Sweep cut
• Fillet
• Appearances

Assembly of Chopper:

• Initially, the Chassis part is inserted in the assembly by using insert parts in the option. After that the part is inserted in the assembly environment and clicked ok to fix the chassis.
• After that the other parts of the chopper are inserted into the assembly and given possible mate conditions.

Features used to assemble Chopper

• Mates
• Insert part

Rendering:

• Rendering is the process of creating realistic images of the Photorealistic model with the environment.
• In the photorealistic model some of the mate conditions and positions are changed to render realistic models.
• Then the photorealistic model is rendered into realistic images with different views.

Rendering has been done in two ways in solidworks. The following are the two ways:

• Solidworks Photoview 360
• Solidworks Visualize

Photoview 360:

PhotoView 360 is a SOLIDWORKS add-in that produces photo-realistic renderings of SOLIDWORKS models. The rendered image incorporates the appearances, lighting, scene, and decals included with the model.

Visualize:

SOLIDWORKS Visualize is a suite of standalone software tools that combine industry-leading rendering capabilities with design-oriented features and workflows that enable easy and fast creation of visual content for designers and engineers.

Conclusion:

Hence, the parts of the chopper are modelled and inserted into the assembly environment and the chopper is assembled. The realistic image was rendered with the use of the Photoview 360 & Solidworks visualize.
