Fender Design - Wheel Arch Challenge

REPORT ON WHEEL ARCH

Objective: To measure the clearance between fender wheel arch and wheel outermost edge.

Wheel Arch

Wheel arches are the semicircular part of a vehicle's bodywork that allows for the wheels to be accessed. In other words, it's the metal part above the wheel. The wheel arch is an integrated part of a fender assembly. Wheel arches are also known as mud guards as they act to prevent dirt and other substances from getting up onto the vehicle itself.

European Regulation:

European Regulation Requirement:

• The value of ‘L’ should be greater than 10 mm at all five sections to satisfy the European regulations.
• The value of ‘a’ shall be more than 5 mm at S_B and S_C.

Sr. No.	Points	Required length (L) in mm	Obtained Length (L) in mm	Remark
1.	SA	10	10	Pass
2.	SB	10	10	Pass
3.	SC	10	0.113	Fail
4.	SD	10	-2.91	Fail
5.	SE	10	-6.04	Fail

Sr. No.	Points	Required length (a) in mm	Length (a) in mm	Remark
1.	SA	5	27.83	Pass
2.	SB	5	44.76	Pass
3.	SC	5	38.36	Pass
4.	SD	5	42.69	Pass
5.	SE	5	47.69	Pass

CONCLUSION:

The obtained value clearance does not satisfy the European standard regulation except the S_B and S_C which is 10mm. Hence the engineer has to change the curvature of the fender.
