ABSTRACT

This project involves the design, assembly, and rendering of American chopper model, American chopper is designed and assembled in solid works 2018 and rendered using photo view 360 and solid work visualizes to give a realistic of its model.

MODELLING

The chopper is built through features based solid modeling and surface modeling features and consists of the following components.

1. Transmission belt
2. Kickstand
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

Transmission belt

It is used to transfer the power from engine to gearbox.

Features involved

• Sketch
• Offset
• Extrude
• Fillet

Procedure

• Sketched in a front plane and give horizontal vertical tangent relations to a fully defined sketch.
• Using smart dimensions to sketch is defined with given dimensions and gave offset entity to the sketch.
  The sketch is extruded and the fillet is applied by selecting all the edges matte rubber is used as a material reference.

Kickstand

The kickstand is used to support the chopper

Features involved

• Loft
• Dome
• Extrude boss
• Extrude cut

Procedure

• Sketch ellipse at the front plane. gave relation to orient inside the 2d sketch.
• Sketch splined at midplane(right). ensured the bottom spline handle is horizontal.
• Sketch a reference plane at the top end of the spline and ensured it is normal to it.
• Sketch ellipse at the reference plane. pierce relation is applied to the ellipse and spline.
• Apply domes at the respective faces of the ellipse.
• Cutout at the larger end of part by sketching rectangle at the midplane. Give extrude cut and apply through all both options.
• Create a mid-point line at the smaller end of the part and split the bottom face to make the part flat face.
• A sketched circle at top plane to create a pivot point. extrude the sketch to the net surface. apply fillet
• Change the appearance to the chrome plate.

FRONT FENDER

The front fender is used to protect the front wheel from hard particles, dust, and mounted above the wheel below the fork.

Features Involved

• Sketch
• Offset Entities
• Trim Entities
• Revolve
• Split

PROCEDURE

• Create a three-point arc and apply relations. Offset the entity to 6mm inside and enclose the edges of the arc using extend entities and power trim.
• Draw a reference sketch for the axis of revolution. and give revolve extrude. Using directions 1 and 2 option to make a relevant sketch.
• Apply appearance to sienna.
• Sketch spline using dynamic mirror entities at the front edge of the fender and apply dimensions and ensure the spline handle is vertical to the part.
• Check the curvature is clean and hide the show curvature. apply the split tool to cut parts and followed the same procedure for the bottom edge.
• Apply fillet at the edges of the fender.

REAR FENDER

The Rear Fender is mounted above the Rear Wheel and has customized painting based on the theme of the copper.

Features Involved

• Sketch
• Offset Entities
• Trim Entities
• Revolve Extrude
• Split

PROCEDURE

• A three-point arc was created as per the given geometry. The sketch was revolved using both the directions 10mm in one side and 140 mm on other.
• Using a three-point arc the part is spilled and the fillet is applied.
• The shell feature is used on the inner side of the fender.
• Graphic rear fender file is imported and the sketch is used to create a projected image using a curve split line and the face is changed to standard white color appearance.

OIL TANK

Oil Tank is Hollow Solid Model created using the following features

Features Involved

• Boss Extrude
• Combine
• Fillet
• Shell

PROCEDURE

• A 2D Sketch is created and then extruded on both directions
• A new sketch is created and extruded through all both the directions
• Combine feature is used to common the both extrude Fillets are applied at the edges and Shell feature is applied with thickness and previewed using the cut section to ensure shell is applied
• Appearance is changed to sienna, white at the edges, and for the graphic oil tank.

CHAIN

This model is approached through creating Sketch blocks and Linear Pattern and mirrored along the Front plane.

Features involved

• Sketch Blocks
• Extrude
• Curve Driven Pattern
• Mirror

PROCEDURE

• A runaway sketch is created at the midplane and the is used to save as separate blocks a chain 1 and 2.
• The blocks are inserted on to the 2D sketch created on the midplane and applied certain relations to make coincident with the curve.
• The blocks are then extruded and fillets are applied at the faces of the pin.
• The linear pattern is applied along the curve (Curve driven pattern) and some extrudes are drawn manually to perfectly align with the chain path.
• Later the solid bodies are classified into chains. plates and pin in separate folders and the chainplates are mirrored using mirror entity.
• Chrome Appearance is applied to the chain.

PEDAL

The Pedal model is mounted external to the chassis on both sides which provides as a footrest to the riders.

Features involved

• Extrude
• Fillet
• Linear Pattern

PROCEDURE

• The 2D sketch is extruded and a new sketch is created and the Revolve Boss feature is applied.
• Dome is applied at the end face of the revolved part and chamfer (asymmetric in both directions) applied to the other two parts
• Fillets are applied and the new sketch is created using offset entity and extruded by offset from the face
• Fillets are applied to the newly created extrude feature and the Linear pattern is applied to four instances
• Ensure all the edges are applied with necessary fillet

REAR WHEEL

Rear Wheel are broad and are one of the most custom-made components in the chopper and has various rim style but the chopper is famous for its spider-webbed designed with its chromium alloy.

Features involved

• Revolve
• Extrude
• Cut Extrude
• Cut Revolve
• Combine
• Circular Pattern
• Fillet
• Chamfer

PROCEDURE

• Five Solid bodies are designed namely Rim, Rotor, Caliper, Sprocket, Tyre.
• Rim is developed using Revolve and a circular pattern is applied to make a spider web-shaped rim wheel.
• The rotor is Designed and the necessary pattern is sketched.
• A Caliper is designed on the rotor by applying the necessary Chamfer features.
• Sprocket is sketched over the rim for chain assembly.
• Finally, the Tyre is designed above the Rim by applying a cut extrude pattern.
• Appearances are changed and Part is saved.

FRONT WHEEL

• Front wheels are designed the same way as Rear Wheel and attached to the front fork with fixed rotation along the fork to allow the chopper to make the turn.
• The Wheel rim also has a spider web shaped and has matte rubber tire with Profile cutout to provide friction between the tire and the road.

RENDERING

Different scenes were created by adding new camera views.

Visualize project is used to create a realistic environment and the rendering is done by adjusting the casualization, brightness, gamma, depth of view and focus with clean and high definition rendering image backgrounds.

The rendered images are attached below with different environments and backgrounds.
