MODELLING AN AMERICAN CHOPPER USING SOLIDWORKS

1.Objective

The objective of this product is to model the American Chopper Bike and to learn how to use the SOLIDWORKS software.

And use Photo View 320 to render the chopper to give it a realistic look and feel (Visualize 360 was not available with Solidworks)

Introduction

The design of this American chopper involves modelling of various parts and the create an assembly of them with proper alignment.

These parts include

Chassis

Engine

Kickstand

Pedal

Transmission belt

. Oil tank

Rear Wheel

Rear Fender

Chain

Gas Tank

Front Fork

Front Wheel

Front Fender

3.Approach To Design

The design of the bike is done by following steps:

To design all the parts of the bike.
To assemble all the modeled parts.
To create camera set up light settings etc.
To do the rendering of the bike using photoview 360.

MODELLING OF THE PARTS WAS DONE USING FEATURES LIKE

1. 2D-Sketches: This feature helps you create any geometry which is 2D and the
created 2D geometry can be controlled by applying relations and these
sketches can be modifies using various sketch tools.

2. Boss Extrude: This feature allows us to take our 2D sketch and convert it into
a 3D solid body by adding a third dimension of height/thickness to it.

3. Revolved Boss: This feature allows us to create a 3d object about an axis to
create a solid body.

4. Sweep: This feature creates a base, boss, cut, or surface by moving a profile
(section) along a path

7. Offset: This feature helps us offset the selected sketch entities by a given
distance.

8. Convert entities: This helps us convert the edges or faces of a 3d model to a
2d sketch for our further use.

9. Loft: This feature helps us create a transition between profiles.

10.Dome: This feature helps us create a dome like structure on the selected faces of
the sketch

11. Fillet: This feature helps us create an external or internal rounded part on the
component.

12. Knit: This feature helps us combine two or more faces and surfaces into one.

13. Combine: This feature helps us combine two or more solid bodies into one.

14.Shells: This feature helps us create a hollow part out of a solid body.

15. Surface Trim: This helps us remove the unwanted material of the surface.

16. Split: The Split Line tool projects an entity to surfaces, or curved or planar faces. It divides a selected
face into multiple separate faces.

17. Chamfer: This feature helps us creates a beveled feature on selected edges,
faces,

or a vertex.

MODELLING OF VARIOUS PARTS IS DONE AS FOLLOWS

Transmission Belt:

For designing this Belt , sketch thediagram of the belt and extruding the sketch using the option available Boss Extrude option present in features tab.

Kick Stand:

The design of kick stand is made by using the Loft option.Here we also use the Dome option to create a dome type ends.

Front Fender And Rear Fender

Fenders are designed using simple sketch which is converted to solid 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 options like Boss extrude, well as circular patter top create the rims , Cut Extrude which helps top remove the sketched material.Revolve is also used Fillets are used to prepare the edges.

Chassis

Chassis is designed with the help of simple sketch made using on different planes and are extruded using the sweep to create hallow tube like structure individually and combining them to form a single solid .

Front Fork

Designing this model involved with bose exrtude, swept bosebase and variors extude features.

Engine

This Design involves several sketches on different . Features like Bosslextrude, 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.(Engine was rendered using photoview 360)

Gas Tank And Oil Tank

The design of gas tank model involves various options like surface loft, surface sweep, surface extrude surface knit, which helps to develop a hallow tank as shown in figure.

The Oil Tank uses a simple extrude feature along with shell feature and a few fillets.

Pedal

This model was designed with spline feature for 2d sketch , linear patterns , bose extrude and revolve features are used for creating the 3d model.

Chain

For this model, 2d slot blocks to create chain slots were created which were later merged with several other slots using extrude feature to interlock and create the chain which was then joined by an extrude feature.
