Fender Design

FENDER DESIGN:

AIM:

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

FENDER:

• A fender is the part of a car that protects and frames its wheels and keeps mud from splashing it.
• It is an aesthetic component/part of a car that frames the wheels. Prevention of sand, mud particles, and other road contaminants from being thrown into the engine compartment and also to the pedestrians by the rotating tires are the main purpose served by the fenders.

TYPES OF FENDERS:

1. FULL BUMPER TYPE:

• These types of fenders were used in earlier models of vehicles. They contribute to the major increment of the steel weight by just covering the front headlights with respect to the bumper region. The problem associated with this kind of fender is there is a lot of wastage in the blank and every inch of a material is a cost to the industry.

2. HALF BUMPER TYPE:

• These fenders are mainly used for serving the purpose of cost-cutting and reducing enough proportions of the steel wait resulting in a reduction of the weight of the vehicle slightly. They can be economically manufactured, i.e by slightly increasing the blank size, we can produce two fenders at a time.

Areas to be considered while designing a fender:

1. Drip area
2. Bumper mounting area
3. Sill mounting area
4. A pillar mounting area

Drip area :

• Drip area mounting is the important part in the fender . this mounting is attached to the engine compartment of the car . fender drip area is mounted via weldnuts to the engine compartment .a min of 150mm distance is kept from the front side and a distance 300mm or less can be kept on the rear side . the total length of drip area from the top of fender should be less than 40mm , this is to avoid the springback during the manufacturing . the edge of the mounting should atleast 10mm away from any nearby component in the engine . a rigidity bead is provided at the end to increase the strength of the mounting .

DESIGN OF SILL MOUNTING AREA :

• Sill is the panel directly below the bottom of the door supporting the floor and may be used to combine the floor and the body . The bottom end of the fender is mounted on the sill body for reinforcement of the fender panel , thus the sill mounting position is designed with holes and emboss . M5 fasteners are used to fix the fenders on the sill body.

DESIGN OF BUMPER MOUNTING AREA :

• Bumper mounting area is used to fix the plastic bumper to the fender with the help of the fasteners

DESIGN OF A-PILLAR MOUNTING AREA :

• The A -pillar is the structural pillar that combines the body to the roof . this make the sides of the windshield rest . front fenders are fastened to the A -pillar to form a robust structure

DESIGN OF BAFFLE MOUNTING AREA :

• Baffle mounting or mudguard are clip fit type 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 clips which are made up of plastics .
