Design of American Chopper

Designing of American Chopper

Objective: - Drafting and designing the American Chopper Bike using the SOLIDWORKS tool.

Introduction:-

The Design of American chopper Bike involves creating the individual parts initially and assembling them together with proper connections and alignment. The individual parts involved in designing the Chopper Bike are as follows.

• Chassis
• Engine
• Kickstand
• Pedal
• Transmission belt
• Oil tank
• Rear Wheel
• Rear Fender
• Chain
• Gas Tank
• Front Fork
• Front Wheel
• Front Fender

Each part design has involved different options which will be explained in detail below and the assembly flow chart is as follows:

The Designing of this Chopper bike start from simple boss extrude and gradually increase the difficulty level for creating the parts

Transmission Belt:-

Transmission belt used in bike to transfer the mechanical energy obtained at engine shaft to the transmission gears.

For designing this Belt we simply sketch the line diagram of the belt and extruding the sketch using the option available Boss Extrude option present in features tab.

Kick Stand:-

Kick stand is also called as the side stand of the bike where it helps the bike to stand on the road

The design of kick stand is made by using the Loft option where it creates the line sketch into hallow tube like structure. The sketch is made on different planes to obtain the tube using loft option. Here we also use the Dome option to create a dome type ends.

Pedal:-

Pedal is a type of foot rest on the bike which is created simply by sketching the line diagram and applying Boss extrude. During this part creation we also linear pattern option which helps to create the similar objectives for multiple times in single line at a particular interval or fixed numbers.

Oil Tank:-

The purpose of oil tank is to store the required fluid helps in combustion in engine. The design of this tank involve a simple sketch and a Boss extrude option in this design we also use the combine option which helps to combine the two separate solid bodies to appear as a single body. The shell option present in the features tab helps to remove the solid material inside the part and creates the shell structure with respect to the given thickness value.

Chain:-

The design of chain involve creating the block of plates which can be imported into the main part sketcher for ‘n’ number of times and extrude them in accordance with the requirement. For designing of the chain we use the curve driven pattern where the repeating of the object follows the curved path of any type.

Front and Rear Fender:-

Fenders are designed by using simple sketch which is converted to 3D object by using the Revolve option available at feature tab which helps to create a circular object for a required angle. All the sharp edges are made curved using the fillet option. Split option which is used to split and remove the unwanted material from the final object.

Wheels:-

Wheels are designed using the multiple options like Boss extrude, Cut extrude which helps top remove the sketched material, revolve and circular pattern to create the Rim. Fillets are used to prepare the edges.

Chassis:-

Chassis is the base part of the Bike where every part is fixed. Chassis is designed with the help of simple sketch made using on different planes and are extruded using the sweep option where we get the hallow tube like structure individually and combining them to form a single solid object. As shown below.

Front Fork:-

The design of front fork involves the simple sketch of line and it is formed to solid object by using the options like revolve, boss extrudes, Mirror and combine.

Engine:-

The most complicated part in the bike design is the design of engine. It involves various sketches on different planes are converted to 3D objects using all above options like Boss extrude, cut extrude, mirror, pattern, sweep. Specially for creating the exhaust vents we use composite curve option which is used to create a curve where the two curve extrudes from 2 different planes meet.nad that joint forms as another curve to form a single curve .

Gas Tank:-

It is hollow tank with a seat on it. The design of gas tank like sheet metal design which involves various options like surface loft, surface sweep, surface extrude, surface knit, which helps to develop a hallow tank as shown in figure.

Assembly: -

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

In solid works we can add the material appearance to each individual part and get the realistic viewing effect using photoview360 where we can adjust the viewing direction using the camera option and place the model in realistic environment and render the image as shown below.
