Introduction

Wheel arc calculation is necessary for the fender design to pass the local regulation which are based on the local road conditions.

Wheel arch is a semi-circular area in fender. It should have a clearance between tyre and wheel arch. So, it doesn’t touch the wheel arch area during suspension. The clearance value differ from region to region

European Regulation Standard:

The clearance value will be more than 10mm at 30 degrees at forward and 50 degree at backward and line 150mm above X-axis and Mid-point between 50 degree and line above 150mm.

SB plot 10mm distance

SA plot 10mm distance

SC plot there is 3mm clearance

SD plot there is 0.25mm clearance

SE Plot there is -3.4mm clearance

Conclusion

we can say that the fender will not pass the standards
