Fender Design - Wheel Arch Challenge

Objective: Calculate the Wheel arch area to prove whether the given fender of car will Pass the European standard or not.

Note: We can't able to calculate wheel arch area because we don't have enough data.

European Standard for Wheel Arch :

The Clearance L as Shown in above fig at all the five section SA-SA, SB-SB, SC-SC, SD-SD and SE-SE

should be greater than 10mm.

Wheel Arch:

.Wheel Arch is the Semi circular part of the 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 projection of water , mud and stones.

. For the vehicle to has its use permit in different countries, the Wheel arch of fenders must be compliant with the standard and regulations set by the respective countries.

Obtaining Result:

Sketch is drawn on the wheel face as per the European standard Provided and Projected on the wheel arch at section SA,SB,SC,SD and SE to measure "L", "a" and wheel arch area.

Obtaining the value of clearance "L" for the given wheel and fender at SA.

The Value of "L" at SA=10.000mm

. Measuring "L " for the given wheel and Fender at SB.

The value of "L" at SB= 9.9490mm

. Meaurig "L" for the given wheel and Fender at SC.

The value of "L" at SC=-0.112637mm

. Measuring "L" for the given wheel and Fender at SD:

The value Of "L"at SD=-2.8220mm

Measuring "L" for the given wheel and Fender at SE:

The Value Of "L" at SE=-5.864mm

Clearance "L" obtained at Section SA, SB,SC,SD and SE.

SECTION Clearance "L" (in mm) Comments

SA 10.000mm Pass

SB 9.9490mm Fail

SC -0.112637mm Fail

SD -2.8220 mm Fail

SE -5.8640mm Fail

Conclusion:

From the Table, the given fender doesn't pass the European standard for wheel arch area at sections SB, SC, SD and SE.
