Fender Design - Wheel Arch Challenge

from the above input we have to calculate the wheel arch gap between the wheel and the fender to do that firstly we have created a sketch which is normal to the wheel outer part then we have made the lines according to the point on which we have to measure the arc and then we have also created the line parallel to the horizontal axis then we made the projection curve. the point is projected on the line and we project the point on fender body then we measure the wheel arch gap between the given projected point and the point on datum plane

the vertical line is called SA 30 degree more than vertical line is SB the SC line is 50 degree less than SA

SE line is ploted on the point which is 150mm above from x axis on fender arch SD line is biasecting linr to the SC andd SE

the distance is just bellow

SECTION CLEARANCE RESULT

SA 9.95 FAIL

SB 10 PASS

SC -0.114 FAIL

SD -2.89 FAIL

SE - 5.99 FAIL

we have also measure the gap between between the wheel arch and the wheel

SECTION GAP

SA 29.98

SB 46.13

SC 33.93

SE 47.63

conclusion

From the above results obtained, we can conclude that the given fender doesn't pass the European Standards for Wheel Arch area.

With this result, the styling team is required to modify the surface of the fender such that the clearance "L" at sections SC, SD and SE is greater than 10 mm by increasing the curvature at those sections towards the outside.
