Fender Design - Wheel Arch Challenge

Aim: To Calculate the Wheel Arch gap at required points and check whether the car passes the European standard.

A. Wender wheel Arch:

A Fender wheel arch, also known as a wheel well or fender flare, is a curved extension on a vehicle's bodywork that covers the wheel and tire. It is typically found on trucks, SUVs, and other off-road vehicles, and its primary function is to protect the vehicle from debris, mud, and other elements that can be kicked up by the wheels while driving. Fender wheel arches can be made of various materials, including plastic, fiberglass, or metal, and they can be added as an aftermarket accessory or come standard on some vehicles. In addition to their practical function, fender wheel arches can also be a design feature, adding a rugged or sporty look to the vehicle.

The European regulations requires a pre-determined clearance or a minimum distance of 10mm to be maintained between the fender and respective tyre at particular points, along the tyre profile as shown below:

B. Steps:

1. Draw horizantal And vertical line By making Centre of the wheel arch as the centre.

2. Draw necessary line with angle according to european Standard.

3. Find Intersection point of the the line and fender.

4. Project these point on fender body.

5. Measure distance between wheel and fender.

C. Distance between the points:

1. Distances between the points L-A

= 9.9490 mm (Fail)

2. Distances between the points L-B

=10.00 mm (Pass)

3. Distances between the points L-C

=-0.113949 mm (Fail)

4. Distances between the points L-D

= 2.8875 mm (Fail)

5. Distances between the points L-E

= 5.9973 mm (Fail)

Conclusion

The given design doesnot satisfies all European standards. Therefore, this fender cannot pass the European standards. The design should be reverted back to the designer Asking him to modify the design
