FENDER DESIGN

Objective : The main object of this project is to design the BIW(Body in white) of front fender using the fender skin data and master section as the into data by using NX CAD.

Introduction : Fender is the American English term for the part of an automobile, motorcycle or other vehicle body that frames a wheel well. Its primary propose is to prevent sand, rocks, mud, liquids, and other road spray from being thrown into the air by the rotating tire. Fender is typically rigid and can be damaged by contact with the road surface.

Sticky materials, such as mud, may adhere to the smooth outer tire surface, while smooth loose objects, such as stones, can be become temporarily embedded in the tread grooves as the tire rolls over the ground. These materials can be ejected from the surface of the tire at high velocity as the tire imparts kinetic energy to the attached objects. For a vehicle moving forward, the top of the tire is rotating upward and forward, and can throw objects into the air at other vehicle or pedestrians in front of the vehicle. Fender is a front outer side member of a car, which covers the wheel side. It has so many small features with ups and downs.

The Importance of car Fenders :

The fenders are an intricate sheet of metal covering the wheel well of your car. Fenders are designed in a manner to provide resistance against wind and other roadside debris. When you travel on rough terrains tour vehicle might get minor scratches and dents which look no better. Frequent road bumps can cause your cars paint to chip off which needs a paint job done. The car fender are located on either side of the front and rear wheels. The front car fenders begin where the front door hinges run and end just before the bumper. The rear car fenders begin where the back doors close and terminate before the back bumpers.

Types of Fenders : There are two types of fenders.

Full Bumper Type
Half Bumper Type

Full Bumper Type :

This type of bumper is not commonly used because this design is more scrap producing one during manufacturing. The blank of steel or aluminum used to produce this type has more wastages. This type is not economically good to manufacture.

Half Bumper type :

This types of fenders most commonly used. The cons of full bumper type is satisfied in this design, and the blank area of wastage while producing the part is drastically reduced by scrap management.

Purpoes of Fender :

Cleanliness : Protect the car, occupants and passers by from items, water, mud, snow, ice, thrown off the tires as you drive.

Safety : Protects pedestrain from the wheel, e.g. its better to be it by a laterally moving fender than a rolling tire, keeps loose, streaming items from being wrapped up in a rolling wheel.

Aerodynamics : Smooths the car profile so you don't get a lot of drag off the uncovered wheels. Some fenders are enclosed on the side for this.

General Appearance : Looks better with fender, gives a finished look, looks more streamlined.

Front Fender Desing : The given master section to create the drip area and for the still mount, Bumper mount and A-pillar mount create your own design according to the engineering standard.
