Fender Design - Wheel Arch Challenge
WHEEL ARCH CHALLENGE
Aim :
To Calculate the Wheel Arch Area by given fender and Wheel Model Design and Prove whether the car will pass by using European standards or Not.
Introduction :
- The wheel arch is the semicircular part positioned above the wheel of a vehicle.
- Designing of wheel arch is the clearance between wheel and fender during the vehicle bump conditions.
- During Rotating Wheels can throw the mudrocks, dirt or water so the fender can prevent the car.
European Standard Regulation Requirement :
As per European Standard Method Given requirement chart given below,
Procedure for Calculation :
- As per given requirements, Clearance between wheel and Fender is 'L' clearance value should be greater than 10mm.
- Wheel Gaurd Value is 'A' it was the clearance between wheel arch and wheel distance the value more than 5mm.
- Measure clearance L at Sections SA-SA, SB-SB, SC-SC,
SD-SD, SE-SE as per given chart value. - At a line of SA angle is 90° and the SA to SB is 30° Forward and SA to SC is 50° Rearward from the central vertical axis of wheel.
- Center Axis line taken by the value is 150mm for SE.
- And the SC to SE midpoint is SD line taken.
Sketch View :
Japanese Standard compatibility:
The Japanese Standard requires the distance between the wheel and fender to be a minimum of 5mm at 3 points as shown in the above figures. Since the clearance at point 3 is 4.1mm. The part has failed to satisfy Japanese Wheel Arch Standards.
American Standard compatibility:
The American Standard requires the fender to be at a minimum distance of 10mm from the outer surface of the wheel at points at every 10 degrees from the -20degrees to 180degrees of the wheel center.
More than 6 values are less than 10mm, hence the part has failed to satisfy the American Standard for wheel arch
Calculation:
we have to consider the europian regulation standard calculation.
1. Value For 'L' :
SA value is 9.9490 mm
SB value is 10.0000 mm
SD value is 2.8875 mm
SE value is 5.9973 mm
Result :
As per the requirement SB is Passed and SA, SD, SC, SE Failed.
Calculation:
2. Value for 'A' :
SA angle of 90° measure value is 27.8310 mm
SB angle distance from SA to SB is 30° angle and the measure value of distance is 44.7577 mm
SC angle distance form SA to SC is 50° angle and the measure value of distance is 38.3599 mm
Result :
As per the requirement SA, SB, SC is passed.
Conclusion :
Hence, we declare that European standard method this fender design didn't passed by given requirements and need to modified the fender design.
