Fender Design - Wheel Arch Challenge
AIM : To calculate wheel arc radius for the given model and check whether it passes the European standard oo not.
ABOUT WHEEL ARC : Wheel Arch is an arch shaped cavity in the fender bod, which houses a wheel. The main intention for the calculation of wheel arc radius is to position the wheel inside the fender body , because during motion the car tyres will tend to throw particles present on the road like sand, mudrocks, liquids etc
It is a semicircular profile above wheels designed for enclosing tire within the fender. The wheel arch is designed considering all possible motions the tire undergoes while the vehicle is in motion. The wheel arch also ensures stopping any debris that could possibly fly outside the wheel well and hit pedestrians.
EUROPEAN STANDARD FOR WHEEL ARCH

RULES FOR EUROPEAN STANDARD
By the given part file I prepared the wheel arch calulation according to European rules

ABOUT LINE SA
The gap between line SA and wheel arch is 9.9490 mm

ABOUT LINE SB
The gap between line SB and whell arch is 10.00 mm

ABOUT LINE SC
The gap between line SC and wheel arch is 0.0100 mm

ABOUT LINE SD
The gap between line SD and wheel arch is -2.8875 mm

ABOUT LINE SE
The gap between line SE and wheel arch is -5.99973 mm

TABULATION
| SECTION | REQUIRED DISTANCE | CALCULATED DISTANCE | RESULT |
| SA | 10 mm | 9.9490 mm | PASS |
| SB | 10 mm | 10.00 mm | PASS |
| SC | 10 mm | 0.0100 mm | FAIL |
| SD | 10 mm | 2.8875 mm | FAIL |
| SE | 10 mm | 5.9979 mm | FAIL |
CONCLUSION
Acooding to European requirement the wheel arch is not good for manufacturing ,so styling team oo design team should work on section SC,SD and SE.
