Photo Realistic Rendering

MODELLING OF AMERICAN CHOPPER ON SOLIDWORKS

OBJECTIVE

• The main objective of the project is to create a model of the parts and assemble the parts for Chopper by using Solidworks.
• To create a Photorealistic model of the Chopper and Render the chopper by using Solidworks Photoview360 and Solidworks Visualize.

PART MODELLING

Part Modelling is a process of creating a virtual prototype of something by modelling each individual parts separately, which can then assemble together to create a model of the final product. In this project the different parts of Chopper are modelled and then assembled together to form a Chopper. This type of modelling is called Part Modelling.

PARTS TO BE MODELLED FOR CHOPPER

The following parts of the Chopper are modelled in Solidworks and assembled

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
13. Gas Tank

1.Transmission Belt

The Transmission Belt in the Chopper is used to transmit the power from the Engine to the Gearbox. The Transmission Belt is shown below,

Features used to create Transmission Belt

• Sketch
• Offset
• Extrude
• Fillet
• Appearances

Sketch

Sketch is the 2D representation of the model with respect to the plane/view from the outside of the model. In solidworks there are different sketch options available to create a sketch. These are known as Entities in solidworks. The entities which available in solidworks are Line, Arc, Spline, Circle, Rectangle.

Offset

Offset one or more sketch entities, selected model edges or model faces by a specified distance. For example, you can offset sketch entities such as splines or arcs, sets of model edges, loops and so on. You can also offset finite lines, arcs, and splines.

Extrude

Extrude is a type of feature available in solidworks to convert a 2D sketch into 3D models.

Fillet

Fillet creates a rounded internal or external face on the part. You can fillet all the edges of a face, selected sets of faces, selected edges, or edge loops.

2.Kick stand

Kick stand is nothing but a component for supporting a bicycle or motorcycle when not in use. It is also known as side stand. The Kick stand is shown below,

Features used to create Kick Stand

• Sketch
• Loft
• Dome
• Extrude Boss
• Extrude Cut
• Fillet
• Split
• Appearances

Loft

The Loft feature in solidworks allows you to generate complex geometry in a single feature. It does this by interpolating surfaces between various cross-sections of a model. These cross-sections can be sketches, faces, or edges. In the loft interface, these cross- sections are considered as "Loft Profiles".

Dome

A Dome is a curved formation or structure. Faces to Dome. Select one or more planar faces. You can apply domes to faces whose centroid lies outside the face. This allows you to apply domes to irregular shaped contours.

Extrude Cut

Extrude cut is another cool feature which helps to remove materials from the 3D model. It is just the opposite to extrude boss/ base feature, because it cuts a sketch profile while extruding. You can cut in both directions and mainly used for creating holes, channels, slots etc.

Split

The Solidworks Split Line tool is used to project an entity (sketch, solid surface, face, plane, or surface spline) onto another surface or curved/ planar faces on multiple bodies with one command.

3.Front Fender

Front fender is a part mounted on the fork above the wheel to protect the rider and the other parts of chopper from debris and the foreign particles. The front fender is shown

Features used to create Front Fender

• Sketch

Trim

Trim tool is mainly used to removing the unwanted portions or parts in the design sketch. All trim is available with 2D sketches and 2D sketches on 3D planes. The trim tools are of different types which are Power trim, Corner trim. Power trim is used in the fender.

Revolve

Revolve feature is an axisymmetric shape that is created by revolving an open or closed section view by a specified angle around a central axis. The section can represent a protrusion or a cut, that is, it can either add material or take it away.

Dynamic Mirror

Dynamic mirror is the important tool in solidworks. As you sketch the entities, they are mirrored about the pre-selected sketch entities.

4.Rear Fender

Rear Fender is used same as the front fender. The rear fender is mounted on the chassis of the rear part above the rear wheel. It primary purpose is to prevent sand, muds, stones, liquid waste and other road spray from being thrown into the air by the rotating tyre. The Rear fender is shown below

Appearances

Appearances defines the visual properties of a model, including colour and texture. Appearances do not affect the physical properties which are defined by the materials. Each material is assigned with a default appearances that emulates the look of the material.

Combine

Combine is a type of feature available in solidworks. It is used to merge two or more bodies into a single solid part.

6.Chain

Chain is a type of transmission system that is used to transmit a power from the Engine to the Rear wheel. The sprocket is used to transmit the power to the chain. The sprocket is connected with the Shaft with the help of a key. The chain is shown below,

Patterns

The pattern command is used for the replication and improving the overall efficiency. There is different type of patterns are present in the solid works such as Linear patter, Curve driven pattern etc. In this curve driven pattern is used . It is used to create pattern along the planar or 3D Curve.

Surface Trim is used to cut away the unwanted materials from one surface to another.

Surface Knit

Surface knit is used to knit the two free edges/open edges of the surfaces together. Also, it reduces the gap between the two edges of the surface.

ASSEMBLY OF CHOPPER

The Chopper Assembly is done in the assembly environment all the parts which are modelled before being inserted into the assembly environment by using insert component feature. The Components are fixed in the assembly environment based on some reference such as planes, mates etc..

Features used to create Assemble Chopper

• Mates
• Insert Part

Mates

Mates create geometric relationship between assembly components. As we add mates, we define the allowable directions of linear or rotational motion of the component. We can move a component within its degree of freedom, visualizing the assembly's behaviour.

PHOTOREALISTIC RENDERING OF CHOPPER

Rendering is the process of creating realistic image of the Photorealistic model with the environment. Rendering has been done in two ways in solidworks. They are

• Photoview360
• Solidworks Visualize

The rendering image of the Chopper are shown below

CONCLUSION

The parts of the chopper are modelled, then modelled parts are inserted into the Assembly environment and the chopper is assembled by using the Solidwoks. The assembled chopper is rendered using Photoview 360 & Solidworks Visualize.

OUTCOME OF THE COURSE

Understanding the concept of Solidworks and implementing the concept in the project.
