Fender Design - Wheel Arch Challenge

Aim :

To calculate the wheel arch gap at required points and check whether the car passes the European standard.

Objective :

Study about the different wheel arch gap standards.Draw the lines at the required angle and points for the European standard. Measure the distance at each angles and mention given model is pass or fail

Introduction:

Europian Standards

he important parameter which is considered in the designing of wheel arch or wheel is the clearance between wheel and fender during the vehicle bump conditions.

Requirements have been proposed by vehicle and road safety community to the minimum requirement of wheel arc distancefrom the wheel for safety.

The Measuring 'L' for the given wheel and fender at SB- The value of 'L' at SB= 10.0000 mm.

The Measuring 'L' for the given wheel and fender at SA- The value of 'L' at SA= 9.9490 mm.

The Measuring 'L' for the given wheel and fender at SC- The value of 'L' at SC= 0.113949 mm.

The Measuring 'L' for the given wheel and fender at SD- The value of 'L' at SD= 2.8875 mm.

The Measuring 'L' for the given wheel and fender at SE- The value of 'L' at SE= 5.9973 mm.

srno	section	distance/clearance(mm)
1	SB	10
2	SA	9.949
3	SC	-0.113949
4	SD	-2.8875
5	SE	-5.997

Conclusion:-

Negative sign indicates that the wheel arc is behind the wheel

All the section don\'t have the CL L value at least 10mm, only SA is seen to have value 10mm

I have study from the above results, We have conclusion that the fender does not pass the European Regulations, as the Minimum Clearence value of 'L' between the fender wheel arch and wheel for vehicle and Safety is 10 mm and this design does't meet the requirement.
