Photo Realistic Rendering

MODELING AND RENDERING AMERICAN CHOPPER USING SOLIDWORKS

OBJECTIVE:-

• To create different parts in American chopper by using solidworks
• To assemble various modelled parts for the chopper 
• To create photorealistic model and render the model by using solidworks photoview 360 and solidwork visualize.

PARTS TO BE MODELED FOR AMERICAN CHOPPER:-

       The following parts modelled in solidworks and assembly together.

• TRANSMISSION BELT
• KICKSTAND
• FRONT FENDER
• REAR FENDER
• GAS TANK
• OIL TANK
• FRONT WHEEL
• REAR WHEEL
• ENGINE
• FRONT FORK
• CHASSIS
• CHAIN
• PEDAL

Transmission belt:

Transmission belt in the chopper is used to tansmit power from engine  to gear box                             

                

Features used to create transmission belt:

• Sketch 
• Offset
• Extrude
• Fillet
• Appearances

Sketch:

Sketch is the two dimensional representation of the model with respect to the plane in solidworks there are different sketch options to create a sketch for example line, Arc ,Spline, Circles, Rectangles. These are known as Sketch Entities in solidwork

Offset:

offset one or more sktech entities select model edge or model face by a specified distance for example offset sketch entities such as lines, arcs and splines

Extrude:

Extrude is a type of feature to convert 2D sketch into 3D model

Fillet:

Fillet creat round internal and external face of parts you can fillet number of faces and edges 

Procedures followed to create a model of Transmission belt

• Open solidworks software and create new model
• Select front plane and draw a sketch
• The 2D sketch plane is created in front plane and dimensions relations are given to the sketch and sketch the offset command use to duplicate sketch to some distance.
• After the process extrude the sketch from 2D to 3D model.
• Then apply the fillets as per requirements of the transmission belt .
• After that give appearance to transmission belt and save the model.

Kickstand:

It is used to support American chopper and it is also called as side stand

                

Features used to create Kick Stand

• Sketch
• Loft
• Dome
• Extrude boss
• Extrude cut
• Fillets
• Split
• Appearance

Loft:

Loft feature allows to generate complex geometry in single feature by interpolating surface between various cross section of a model these cross section can be face or edge.

Dome:

Dome feature gives smooth face on profile you can apply dome to face whose centroid lies outside the face.This allows you to apply dome to irregular contours

Extrude cut:

Extrude cut is used to remove materials from the 3D models.It is just opposite to Extrude Boss feature you can cut it both directions and mainly used for creating holes, slots etc

Split:

Split tool used to project an entity (sketch, solid, surface, face, plane or surface spline) onto other surface or curved face you are able to split faces on multiple bodies by this command

Procedures followed to create a model of kickstand:

• Open solidworks and creat new model
• Select mid plane (Right plane) draw sketch on it
• Then the 2D sketch is created in the front plane and dimensions are given to the sketch to fully define we will use trim and spline commands are used
• Then creat two new planes and the ellipse are drawn on the new planes as per requirements
• Then use loft command to create loft for kickstand
• Then do extrude cut command to remove unwanted parts for the stand

Surface that are generated from a section curve positioned along a path

Filled surface

Filled surface feature constructs surface path with any number of sides within a boundary defined by existing model edge sketches or curves including composite curves

Surface trim

Primarily used to cut away material from a surface and provide two modes standard and mutual

Surface knit

Surface knit is used to knit the two free edge of the surface together.also it reduce the gap between the two edges of the surface

Process to Create a block

1. create a sketch
2. click make blocks (block toolbar)
3. Select sketch to make blocks
4. repeat step once again

It is used to move body from one place to another

Mirror

By using mirror face with a mid-plane selected only the chosen within the revolve will be mirrored.mirroring bodies can be used whether in a single or multi body part and allows you to select solid geomentry instead of the features and faces in a body In the fork part  the one part of the fork is created and the other part is mirrored.Then the parts are manually combined.

Project curve

Project curve is the kind of 3D cure which is projected on the basis of the two different 2D sketches

Sweep

With the Sweep feature we can create a shape by moving a 2D sketch profile along a 2D or 3D sketch path

Engine:

Engine is the prime mover for the bike. The engine converts a chemical energy into heat energy

and then heat energy is converted into mechanical energy.

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 make it fix the chassis
• After That the other parts of the chopper are inserted into the assembly and give possible mate conditions

                     

Features used to assemble chopper 

• Mates
• Insert part

Mates

Mates create geometric relationships between assembly components as we add mates we define the allowable direction of linear or rotational motion of the component we can move a component within degrees of freedom visualizing the assembly behaviour

Rendering:

• Rendering is the process of creating realistic images of the photorealistic model with the environment.
• rendering can be done in two ways in solidworks.
• Photoview 360
• solidworks visualize.
• In photorealistic model some of the mate conditions and positions are changed to render realistic model.

                    

                    

                    

                    

                    

Conclusion:

• The parts of the chopper are modeled.
• The parts are inserted to assembly environment and the chopper is assembled.
• The realistic image was rendered with the use of the photoview 360 and solidworks visualize.
