Fender Design

FENDER DESIGN

OBJECTIVE:
To design a front fender of a car by following the given master section as per the design considerations of OEM.

FENDER:
A fender is a front outer side member of a car that covers the wheel side. Fender's purpose is to prevent sand, mud, rocks, liquids, and other particles. During the motion, the wheel picks up sand mud, and small stone particles and throws them inside the car, and these fenders will be helpful in preventing them by hitting inside the engine compartment and car body.

Types of fender :
1. Full Bumper Type.
2. Half Bumper Type.

Full Bumper type :
It is not used nowadays because they require bigger size blank to produce the part and large scrap is also produced.

Half Bumper Type :
Half bumper types are used in the present and future also because the blank size is less and the wastage or scrap is less compared to full bumper type fenders.

Areas to be considered while designing a fender:

1. Drip area.

2. Bumper mounting area.

3. Sill mounting area.

4. A-pillar mounting area.

5. Baffle area.

MASTER SECTION:

Designed Data:

Drip area :

Drip area mounting is an important part of the fender. this mounting is attached to the engine compartment of the car. fender drip area is mounted via weld nuts to the engine compartment.

Bumper mounting area :

Sometimes fender is also provided with the cowl area mounting. this mounting is on the top side of the fender.

A-pillar mounting 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.

Baffle mounting area :

Baffle mounting or mudguard are clip-fit types of mounting on the inner side of the fender arch over the Tyre. it protects the car engine compartment and pedestrians from causing injuries from chip-out debris on the road when the car is in motion. they are mounted on the fender using a special type of locking clip which is made up of plastics.

Sill mounting 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.

CONCLUSION :

Thus, all mounting areas for the fender designed from skin data and the master section are done by following all design rules.
