Fender Design - Wheel Arch Challenge

DESIGN OF FRONT FENDER-

OBJECTIVE- To develop the front fender using Nx cad following the design parameters .

INTRODUCTION:

Fender is a front outer side member of a car which covers the wheel side. Fender purpose is to prevent sand, mud, rocks, liquids and other particles. Fender is a closure component, closing the engine compartment and other compartments. The major role of the fender is to avoid the chipping inside the engine compartment. During the motion the wheel picks a sand mud and small stone particles and throws it inside the car and these fenders will be helpful in preventing them by hitting inside the engine compartment and car body. These fenders will have a plastic part which lies on wheel arch area. The fender plays a major role to avoid problems for pedestrian also.Fender are typically rigid and can be damaged by contact with the road surface. It is often also called as Mudguard.Fender is the US English term for the part of a vehicle body that frames a wheel inside it. Its primary function is to prevent sand, mud, liquid, and other materials from being thrown into the air by rotating tires. Fenders are 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 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 vehicles or pedestrians in front of the vehicle.

Types of Fender:-

Fender is basically of 2 types.

1;-Full Bumper type

1:-Half Bumper type

Presently we are using half bumper type. The reason is when we were using a full bumper type fender, the blank which we were using is very big, and we have quite lots of wastage from the blank. But in the case of the half bumper type, the case is the opposite. Here is the amount of scrap production is very low. Because material can makes a major role in automotive industries. when we are using full bumper type it requires more material and weight of the car also increased. so because of that reason we use half bumper type.

A-pillar area :-

The A-pillar area mounting depends upon the A-pillar of the car the mounting can also be provided with ribs to strengthen the part. this mounting is critical in design as it has to be mounted on A-pillar properly

Body side area:-

Another mounting point is created for the body side on the fender this mounting is created such that it can be mounted on the body of he car. it may consist of one or two bolting holes

Sill area :-

Sill area mounting is also an important mounting part.this mounting point is basically on the bottom of the fender. the mounting part should be created such that the fender is firmly attached to the sill
