AIM & OBJECTIVE:

The objective is to design and assemble the various parts of chopper by using solid works.

INTRODUCTION:

• The chopper assembly mainly consists of part modeling.
• The part modeling environment is used up to 95% in chopper assembly
• To model the chopper by using part modeling features.

PARTS TO BE MODLLED:

• Transmission belt
• Kick stand
• Front fender
• Rear fender
• Oil tank
• Pedal
• Chain
• Front wheel
• Rear wheel
• Front fork
• Chassis
• Engine
• Gas tank

ABOUT FEATURE COMMAND:

Features:

• Features are the individual shapes that, when combined, make up the part. You can also add some types of features to assemblies.
• Features include multi body part capability. You can include separate extrude, revolve, sweep features within the same part document.

Features Toolbar:

• Features toolbar provides tools for creating model features. The set of features icons is very extensive so not all of them are included on the default Features toolbar
• Use the layout Tools toolbar to create and edit a layout-based assembly design. The macro toolbar controls macro recording , playback, and editing

Creating a Chamfer and Fillet Feature:

• The chamfer tool creates a beveled feature on the selected edges, faces, or a vertex.
• Fillet is feature tool which is used to rounding of interior or external face along with one or more edges of your design.

Cuts:

A cut is a feature used to remove the excess material in the part or an assembly.

Projected Curves:

A projected curve is typically used either in sweeps and lofts as or guide curve. There are two types of projected curves.

Sketch on sketch: Use two sketches to make single curve.

Sketch on surface: Use a sketch point on a surface.

Split Line:

The split line tool is used to project an entity (sketch, solid, surface, plane, or surface Spline) onto other surface or curved/planar faces. You are also able to split faces on multiple bodies with one command.

Creating Curves through Reference Points:

Creates a curve through points located on one or more planes.

Composite Curve:

From a combination of curves, sketch geometry and model edges.

Deforms:

Use the deform feature to alter shapes of complex surface or solid models, either in a local area or globally, without concern for the sketches or feature constraints used to create the models. Deform provides a simple way to change virtually any model, whether organic or mechanical, and is useful when creating design concepts.

Dome:

Select one or more planar or non planar faces, you can apply domes to faces whose centroid lies outside the face. This allows you to apply dome to irregularly shaped contours.

Elliptical Dome:

Specify an elliptical dome for cylindrical or conical models. An elliptical dome’s shape is a half ellipsoid with a height equal to one of the ellipsoid radii.

Extrudes:

We can extrude the boundary edges of a face of a solid body in a customized direction. You can also use Instant3D and Rapid Sketch to create extrudes.

Library Features:

Library feature is a frequently used feature, or a combination of features, that you can create once and then save in a library for future use. Most feature types are supported, some with certain limitations.

Patterns &Mirroring:

We can use the pattern or the mirror feature to pattern or mirror multiple bodies within the same document. When pattern or mirror features split single bodies into multiple bodies, you can select which bodies to keep and specify which configurations to keep up to date.

Revolves:

Revolves add or remove material by revolving one or more profiles around a centerline. You can create revolve boss/bases, revolve cuts or revolve surfaces.The revolve feature may be solid thin feature or a surface

Shells:

The shell tool hallows out a part, leaves open the faces you select, and creates thin walled features on the remaining faces.

Sweeps:

Sweep creates a base, boss, or surface, by moving a profile along a path. A sweep can be simple or complex.

Appearance:

You can apply appearances to features, face, bodies, and parts. To apply an appearance, simply select the desired appearance from the Appearance Resource list, hold down the mouse button and drag it to the face, feature or part you want to assign the appearance.

Offset:

The offset command is used to create the similar sketch in some distance required.

Trim:

The trim command can be used to remove the excess or extra portion in the sketch trim command basically works based on same reference point, edge etc.

Dynamic Mirror:

This tool allows the user to mirror a sketch about a line while the user is creating the sketch. Depending on the design intent this toll can save immense amount of time.

Linear Pattern:

The linear pattern is used to create a similar model either in linear xyz direction. The pattern is created based on reference edge, face etc.

Circular Pattern:

The circular pattern is used to create a similar solid surface in a circular direction up to user defined instances.

Delete Face:

This command is used to delete unnecessary faces and this feature comes with some options like delete face, delete patch , delete and fill.

Transmission Belt:

The transmission powers the drive system for the chopper, which is either a chain system or a belt system. Chains and belts connect one side, the rear tire. Transmissions only provide power to the rear tire. Most chopper use an open primary system, meaning the belt or chain isn’t covered by housing or casing its left out in the open for all time.

Commands used in Transmission belt:

• Sketch
• Extrude
• Fillet

Kick Stand:

A kickstand is a device on a bicycle or motorcycle that allows the bike to be kept upright without leaning against another object or the aid of a person. A kickstand is usually a piece of metal that flips down from the frame and makes contact with the ground. It is generally located in the middle of the bike or towards the rear.

Commands used in Kick Stand:

• Sketch
• Loft
• Dome
• Cut extrude
• Extrude
• Fillet

Front Fender:

Fenders are panels on a car that are located on the sides of the car in front of the doors. They serve a number of functions, not least of which is aesthetic. Drivers may be most familiar with the fender in the context of a “fender-bender,” a minor accident in which the fenders of a car are dented or damaged as a result of a collision.

Commands used in Front Fender:

• Sketch
• Revolve
• Split
• Fillet

Rear Fender:

Quarter panels are at the rear, with an exception made for dual rear wheel trucks, where the panel at the rear is called a fender. For vehicles with a narrow car body that exposes the tire, the fender is an exposed curve over the top of the tire.

Commands used for Rear fender:

• Sketch
• Revolve
• Split
• Fillet
• Shell

Oil Tank:

Oil tanks can be taken to any of our recycling centers. Oil tank can be very large and will not fit in the recycling center bins whole. To accept them it must be fully drained of any oil and you will need to break up the tank into smaller pieces.

Commands used in Oil Tanks:

• Sketch
• Extrude
• Combine
• Shell
• Fillet

Pedal:

Higher-end bikes are expected to be used with clipless pedals. However, there are several different standards for these pedals, and all of which have a different type of cleat that fits in them. Most cyclists tend to stick with one of these standards across all of their bikes, so they don't have to have multiple sets of shoes.

Command used for Pedal:

• Sketch
• Boss extrude
• Fillet
• Revolve
• Dome
• Fillet
• Chamfer
• Linear pattern

Chain:

A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. A chain may consist of two or more links.

Command used in Chain:

• Sketch
• Extrude
• Circular Pattern
• Fillet
• Mirror
• Keep/Delete Body

Front Wheel:

Command used in Front Wheel:

• Sketch
• Revolve
• Circular pattern

• Chamfer
• Fillet

Rear Wheel:

Command used in Rear Wheel:

• Sketch
• Revolve
• Circular pattern
• Boss Extrude
• Cut Extrude
• Combine
• Caliper
• Chamfer
• Fillet
• Cut Revolve

Front Fork:

Front fork serves as rigidity component just like a frame. Vehicle specific rigidity given to present run out while braking and changing the direction of a wheel though handle operations. Maintain balance of vehicle frames stability and secures straight running stability as well as rotationality of the vehicle.

Command used in Front Fork:

• Sketch
• Revolve
• Linear pattern
• Boss Extrude
• Cut Extrude
• Fillet
• Dome
• Cut Revolve
• Projected Curve
• Mirror
• Combine

Chassis:

A chassis is the load-bearing framework of an artificial object, which structurally supports the object in its construction and function. An example of a chassis is a vehicle frame, the underpart of a motor vehicle, on which the body is mounted; if the running gear such as wheels and transmission, and sometimes even the driver's seat, are included, then the assembly is described as a rolling chassis.

Command used in Chassis:

• Sketch
• Projected curve
• Sweep
• Mirror
• Boss Extrude
• Cut Extrude
• Fillet
• Split
• Combine

Engine:

An engine or motor is a machine designed to convert one form of energy into mechanical energy. Heat engines, like the internal combustion engine, burn a fuel to create heat which is then used to do work.

Command Used for Engine:

• Sketch
• Boss Extrude
• Revolve
• Fillet
• Circular Pattern
• Cut Extrude
• Dome
• Chamfer
• Mirror
• Projected curve
• Composite curve
• Split
• Sweep

Gas Tank:

The gas tank of the vehicle holds the fuel, which makes the car run. The fuel is propelled by the fuel pump. The gas tank can be made out of plastic high-density polyethylene , which can be made into complex shapes, save space, and can improve crash safety. The gas tank can also be made out of steel or aluminum, which is welded from stamped sheets.

Command used in Gas Tank:

• Sketch
• Surface Sweep
• Surface Trim
• Projected Curve
• Surface Loft
• Split Line
• Surface Extrude
• Fillet
• Boundary Surface
• Cut Sweep
• Surface Knit
• Shell

Assembly:

• All the modeled parts are inserted one by one in the assembly.
• Every part should be mate perfectly so that it should be fit to other components.
• The front fork must have a angle of rotation of about +45 and –45 degrees.
• The kick stand should also have an rotation of about 6 degree.

Conclusion:

Thus the various exterior part of the chopper has been modeled and assembled by using Solidworks software.
