Fender Design - Wheel Arch Challenge

* Wheel Arch

Wheel Arch is the semi-circular part of thee fender positioned above the wheel of the vehicle. The design of Wheel arch of a fender should be such that it must shield wheels and protect both passengers' compartment and pedestrians from projectlonof water, mud and stones. For the vehicle to has its use permit…

*European Standards for Wheel Arch:

1. The clearance"L" as shown in above fig at all the five sections SA-SA, SB-SB, SC-Sc, SD-SD and SE-SE should be greater than 10 mm.

2. Wheel Guard Requirement: The value of 'a shall be more than 5 mm at a line 30° forward and 50° rearward from centre vertical axis of the wheel.

4.Obtaining Results:

Software Used: NX 12 (CAD)

Sketch is drawn on the wheel face as per the European standards provided and projected on the wheel arch at sections SA, SB, SC, SD and SE to measure 'L', 'a and wheel arch area.

A.Obtaining the values of clearance "L"

a)Measuring "L" for the given wheel and fender at SB.

The value of "L" at SB=10.00mm

b)Measuring "L" for the given wheel and fender at SA

The value of "L" at SA=9.94mm

c)Measuring "L" cor the given wheel and fender at SC.

The value of "L" at SC=0.113mm

d)Measuring "L" for the given wheel and fender at SD.

The value of "L" at SD=3.0828mm

e)Measuring "L" for the given wheel and fender at SE.

The value of "L" at SE=6.3695mm
