Fender Design - Wheel Arch Challenge

Objective:

Calculate the Wheel Arc area and prove whether the car will pass the standards or Not

Wheel arch:

It is the semi-circular edge of the fender which houses wheel-well. The wheel arch gives access to the wheel and other components attached to it. Also, it allows the tilting of wheels while steering to both sides without causing any interference between wheel and body. The wheel arch is designed in such a way that it allows any possible kind of motion that the wheel can have and prevent any materials that could fly out from the wheel during the motion and also prevent from going to the engine compartment. Thus it has a crucial role in pedestrian safety and the safety of other vehicles.

There are 5 checkpoints on the sections SA, SB, SC, SD & SE as shown.

In all these checkpoints the clearance “L” should be greater than 10 mm.

Measured L values of SA, SB, SC, SD & SE are as given below is:-

SB=10mm It is sufficient to meet European standards.

SA=9.949mm To meet European standards add at least 0.051mm.

SC=0.114mm To meet European standards add at least 9.886mm.

SD=-2.879mm To meet European standards add at least 12.879mm.

SE=-5.976mm To meet European standards add at least 15.976mm.

Other than SB all others have to add more length in the fender.
