Fender Design - Wheel Arch Challenge

1. Wheel Arch:

• Wheel arch is the semi-circular part of the fender located above the wheel of the vehicle
• The design of the wheel arch are there to stop water ingress from getting into tight spots around the wings of the car to prevent corrosion. They also protect any electric or pipe work from the water.
• The wheel arch of fender must be compliant with the standard and regulation set by the respective countries.

2. Objective of the wheel arch challenge:

• Calculate the wheel arch gap required points and check whether the car passes the European standard

3. European standard foe wheel arch

Figure no.2

4. Result

The sketch is drawn on the face of the wheel as per European standard and projected on the wheel arch sections SA, SB, SC, SD, and SE to measure “L”. “a” and wheel arch area.

4.1 Obtaining the value of clearance “L”

Figure no.3

4.2Measuring “L” for the given wheel and fender at SB

4.3 Measuring "L" for the given wheel and fender at SC

4.4 Measuring "L" for the given wheel and fender at SD

4.5 Measuring "L" for the given wheel and fender at SE

5. Final result

Section Based on European standard	Required clearance In (mm)	Actual clearance In (mm)	Result
SA	10 mm	9.9490 mm	Fail
SB	10mm	10 mm	Pass
SC	10mm	0 mm	Fail
SD	10mm	3.4372 mm	Fail
SE	10mm	7.1474 mm	Fail

• We can conclude That the given model does not satisfy European standards on Section SA, SC, SD and SE.
