Fender Design - Wheel Arch Challenge

Aim:Explain the fender arch regulations and verifying whether the given fender arch full fill the standards of the fender arch regulations

THEORY:

FRONT FENDER:

It is a BIW component whose purpose is to avoid water and other tiny rocks or dust splashing into the passenger compartment,fender has no contribution to the stuctural rigidity of the vehicle in camparision to the body frame

• Nowdays fender is desigined in such a way to reduce air drag by fallowing areodynamic principles for improving the performance of the vehicle
• It doesn't provide any structral rigity to the frame but protect both passengers compartment and pedesrains from the projection of water ,mud and stones

WHEEL ARCH:

Wheel Arch is the semi circular part of the fender poistioned above the wheel of the vehicle.For the vehicle to has its use permit in different countries the wheel arch of fenders must be complaint with the standards and regulations set by the respective counries

Diffenent countries has different regulations for fender designs as fallows

European standards for Wheel Arch:

• The clearance L as shown in the above fig at all the five sections SA-SA,SB-SB,SC-SC,SD-SD and SE-SE should be greater than 10mm
• Wheel Guard Requirement :The value of a shall be more than 5mm at a line 30 forward and 50 rearward from centre vertical axis of the wheel

BY using siemens nx (sketch is submitted in the browse)

The sketch is drawn on the wheel face as per the European standards provided and projected on the wheel arch at section SA,SB,SC,SD and SE to measure L ,a and wheel arch area

section	clearance " L " in mm	actual measured length in mm	result
SA	>=10	9.94	fail
SB	>=10	10	pass
SC	>=10	0	fail
SD	>=10	0	fail
SE	>=10	0.7151	fail

Therofoe from the above calculations the given fender design fail majorly in most regions as per the European standards
