Fender Design - Wheel Arch Challenge
Fender Design of Car
Aim: Calculate the Wheel Arch gap at required points and check whether the car passes the European standard
Introduction to Fender: A fender is a semi-circular Arch type curved sheet metal structure which is used to prevent the entry of sand, mud, stones and another particle inside the engine compartment.
Important parts in Fender design:
- Wheel Arch
- Drip Area
- Baffle and ORVM mounted Area
- FRONTAL CRASH regulation and requirements
European Standard for Fender design:
According to European Union, the clearance size L should equal a minimum of 10 mm at every section(OA, OB, OC, OD, OE).
Results during checking of wheel arc gap :
- Clearance for Section OB (L) = 10 mm.
- Clearance for Section OA (L) = 9.9489mm.
- Clearance for Section OC (L) = 0.1137 mm in the inside direction means the wheel is going outside of the fender
- Clearance for Section OD (L) = 2.8787 mm in the inside direction means the wheel is going outside of the fender
- Clearance for Section OE (L) = 5.9755 mm in the inside direction means the wheel is going outside of the fender
Comparing the above Observation and checking whether the car passes the European standard or not:
| SECTION |
MIN REQUIRED CLEARANCE (EU STD) IN MM (WHEEL ARCH GAP) |
ACTUAL CLEARANCE IN MM (WHEEL ARCH GAP) | STATUS |
| OA-OA | 10 | 9.9489 | FAILED |
| OB-OB | 10 | 10 | PASS |
| OC-OC | 10 | -0.1137 | FAILED |
| OD-OD | 10 | -2.8787 | FAILED |
| OE-OE | 10 | -5.9755 | FAILED |
Conclusion: According to the upper observation table, the fender is not passed the required clearance dimension of the Wheel Arch Gap which can fulfil the European standard need which should be a minimum of 10 mm. So this Fender is worthless.
