Fender Design
AIM: To design a front fender of a car by following the given master section as per the design considerations of OEM.
FENDER
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.
The front fenders are separate components whereas the rear fenders are integrated with the body sides.
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.
Design considerations for Front Fender :
- Drip Area
- Sill Mount
- Bumper Mount
- A Pillar Mount
- Splash/Baffle Mount
Most important consideration is a drip area and for creating that we have to follow the given design rules.
Design Criteria :
- Embosses are provided to increase the strength.
- Smooth curves are designed for easy manufacturing of panel.
- Ribs are provided to drip area mount to give structual support and extra strengh.
- Maintain extra 10mm from the flat surface for the fastner holes.
- All fillets should maintain 2 or 3mm radius in most regions.
- Thickness of fender is 0.75mm.
DRIP AREA :
DRIP Area should not exceed more than 40mm or else it would create springback which in result will cause damage to the component which is not a good design.
Two DARTS are created to provided support.
Emboses are provided to increase strength.
SILL AREA :
BUMPER MOUNT AREA:
A PILLAR MOUNT AREA :
SPLASH/BAFFLE MOUNT AREA :
ALL SIDE VIEWS :
