Aim : To Calculate the wheel arch radius for the given Fender model and check for its eligibility to pass the European Standards.
Explanation :
Wheel Arch is an arch shaped cavity in the fender body, which houses a wheel. The main intention for the calculation of wheel arc radius is to position the wheel inside the fender body , because during motion the car tyres will tend to throw particles present on the road like sand, mudrocks, liquids etc. into the air which may harm the pedestrians and cause problems.
European Standard
As per European Standard, The clearence L should not be less than 10 mm at all the 5 points SB, SA, SC, SD, SE
The following values were achieved when measured:
SB-SB - 15 mm , SA-SA - 13.98 mm, SC-SC - 5.8931 mm, SD-SD - 3.2675 mm, SE-SE - 2.3758mm
When compared the values with the European Standards the following results were achieved :
SB-SB - 15 mm ( PASS )
SA-SA - 13.98 ( PASS )
SC-SC - 5.8931 ( FAIL )
SD-SD - 3.2675 mm ( FAIL )
SE-SE - 2.3759 mm ( FAIL )
Conclusion :
Only the Lines SB & SA which is greater than 10 mm from the fender outer, satsify the Eurpean standard whereas the other lines doesnt. Hence we have to discuss with the styling team and give our inputs to change the styling of the Fender to satisfy the European Standards.
Hence, the Given Fender model doesnt Pass the European Standards and need to be modified.
