Fender Design Challenge
DESIGN OF CAR FENDER AND MOUNTING STRUCTURES
FENDER:
Fender is the American english term for the part of an automobile, motorcycle or other vehicle body that frames a wheel well (the fender underside). Its primary purpose is to prevent sand, mud, rocks, liquids, and other road spray from being thrown into the air by the rotating tire. 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
- FULL BUMPER FENDER
- HALF BUMPER FENDER
MOUNTING
- BUMPER
- DRIP
- A PILLAR
- SILL
- COWL
GIVEN DATA FOR THE FENDER DESIGN:
DESIGN CONSIDERATION FOR THE FENDER:
- 150 mm Distance from front end is kept for the headlamps. some time it varies depend upon the car
- 200 mm Distance from the rear end is maintained for wiper assembly. some times it varies depend upon the car
- Engine components should not be visible from outside. For this purpose initially 3 degree of angle and suitable lenght should be provided
- To avoid spring back effect drip depth should be at maximum 40 mm
- The gap between engine compartment and drip area should not be less then 10mm
DRIP MOUNT:
A PILLAR MOUNT:
SILL MOUNT:
BUMPER MOUNT:
BAFFLE MOUNT:
FINAL MODEL:
CONCLUSION:
Thus Fron fender of car is designed with a proper mounting structures by considering all the design parameters.
