Photo Realistic Rendering

AMERICAN CHOPPER

INTRODUCTION

A chopper is a type of custom motorcycle which emerged in California in the late 1950s. The chopper is perhaps the most extreme of all custom styles, often using radically modified steering angles and lengthened forks for a stretched-out appearance. They can be built from an original motorcycle which is modified ("chopped") or built from scratch. Some of the characteristic features of choppers are long front ends with extended forks often coupled with an increased rake angle, hard tail frames (frames without rear suspension), very tall "ape hanger" or very short "drag" handlebars, lengthened or stretched frames, and larger than stock front wheels. The "sissy bar", a set of tubes that connect the rear fender with the frame, and which are often extended several feet high, is a signature feature on many choppers. Here we are going to design, assembly, rendering a chopper with the using of SolidWorks CADD Software.

OBJECTIVES

• Understanding user interference in solidworks.
• Draw the sketches with fully defined and Understanding and implementing shell feature sketch blocks and Linear pattern in Solidworks
• Application of relations to the entities.
• Design all parts of the bike with the reference of planes and saving parts in separate part file, for final assembly.
• Understanding the utility of solidwork tools like Extrude, Extrude cut, Pattering, Revolving, Revolve cut, Trimming, Extend, projected curves, Composite curves, Make pierce features etc.
• Assembling all parts using assembly interference.
• Understanding of mating systems.
• Understanding of photo realistic rendering.

TRANSMISSION BELT

A Transmission Belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Transmission Belt used as a source of motion, to transmit power efficiently or to track relative movement. Transmission Belt are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel.

KICKSTAND

A metal rod attached to chopper, lying horizontally when not in use, that may be kicked into a vertical position to support the chopper when it is stationary.

FRONT FENDER

A curved piece of metal that covers a front wheel of a Chopper.

REAR FENDER

A curved piece of metal that covers a back wheel of a Chopper.

CHAIN

A mechanism in which power is transmitted from an engine to the wheels of a Chopper.

OIL TANK

A oil tank is a safe container for oil of the bike.

PEDAL

A metal frame consist of gear rod for the chopper and to hold the legs of the rider on chopper.

FRONT WHEEL

A circular object that revolves on an axle and is fixed below a chopper to enable it to move easily over the ground and Consist of front braking system.

REAR WHEEL

A circular object that revolves on an axle and is fixed below a chopper to enable it to move easily over the ground. Rear wheel is connected with the engine to get the power to rotate the wheel or move the chopper. Consist rear braking system and a sprocket for the chain.

FRONT FORK

A fork connects a chopper’s front wheel and axle to its frame, typically via a yoke, also known as a triple clamp, which consists of an upper yoke joined to a lower yoke via a steering stem, a shaft that runs through the steering head, creating the steering axis. Fork incorporate the front suspension and front brake, and allow the front wheel to rotate about the steering axis so that the Chopper may be steered. Most handlebars attach to the top clamp in various ways, while clip-on handlebars clamp to the fork tubes, either just above or just below the upper triple clamp.

CHASSIS

A chassis is a chopper's core structure. It supports the engine, provides a location for the steering and rear suspension, and supports the rider and any passenger or luggage. Also attached to the frame are the fuel tank and battery. At the front of the frame is found the steering head tube that holds the pivoting front fork, while at the rear there is a pivot point for the swingarm suspension motion.

ENGINE

A engine that powers the chopper. It consist of pistons, a cylinder block and a head, which contains the valve train. The pistons move up and down in the cylinder block, driven by explosions of a fuel-air mixture that has been ignited by a spark. Valves open and close to allow the fuel-air mixture to enter the combustion chamber. As the pistons move up and down, they turn a crankshaft, which transforms the energy from the pistons into rotary motion. The rotational force of the crankshaft is transmitted, via the transmission, to the rear wheel of the motorcycle.

GAS TANK

A Gas tank (or petrol tank) is a safe container for flammable fluids. Though any storage tank for fuel may be so called, the term is typically applied to part of an engine system in which the fuel is stored and propelled (fuel pump) or released (pressurized gas) into an engine.

ASSEMBLY AND RENDERINGS

Assembling all parts into one assembly file to get final chopper model.
