Fender Design Challenge

INTRODUCTON-

Front fender is part of the vechicle that frames the wheel.the pimary purpose of the fender is to prevent sand, mud, rocks, etc from being thrown away into the air by rotating tire. Fender can be of two types one is full bumper type and other is half bumper type. Nowadays half bumper type fender is typically used. the cost of the sheet metal blank is reduced as we can produce two half bumper type fender in single blank. this also leads to reduce the scrap.

DESIGN PARAMETERS-

The front fender is manufactured as a separate part, this then mounted to the body of car, for this fornt fender basically five mounting parts

1. 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 of 300mm or less can be kept on the rear side. the total length of the drip area from the top of fender should be less than 40mm, this is to avoid the spring back during the manufacturing. the edge of the mounting should at least 10mm away from any nearby component in the engine. a rigidity bead is provided at the end to increase the strength of the mounting.

2.A-pillar mount-

The A-pillar area mounting depends upon the A-pillar of the car. the mounting depends 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.

3. 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 the car. it may consist of one or two bolting holes.

4. 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.

Bumper Mount-

5.Cowl area-

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

CONCLUSION

We have developed front fender with mounting points following the design parameters and mastersection.
