Fender Design - Wheel Arch Challenge

Title of the project: Fender design-Wheel Arch Challenge

Objective: to calculate the wheel arch area of the given fender and prove whether the car will pass the European Standards or not.

Introduction: Wheel Arch is the shaped part of the bodywork of a car or other vehicle that allows the wheel to be accessed, and in the case of front wheels, enable them to be steered. It is the semi-circular part that is positioned above the wheel of the vehicle. It should have the sufficient clearance between the tyre and the wheel arch so that it does not touch the wheel arch area.

European Standards:

1. At all five sections the clearance value should be greater than 10 mm.
2. Wheel guard requirement: The value of ‘a’ shall be more than 10 mm at a line 30˚ forward and 50˚rearward from the central vertical axis of wheel.

Wheel Arch Calculation:

This calculation will be done using European standards as per the instruction in the challenge to be followed.

Procedure: The sketch is drawn on the wheel face and projected on the wheel arch at section SA, SB, SC, SD, and SE and then the clearance value at these section is measured

Obtaining the clearance value ‘L’ at section SA, SB, SC, SD and SE:

At Section SA:

At Section SB:

At Section SC:

Measuring the clearance vlaue'a' for Wheel Guard Requirement

i.) Clearance 'a' at 30° line SB

ii.) Clearance 'a' at 50° line SC

Conclusion:

From the above results we can conclude that the Fender does not pass the European Regulations, as the minimum clearance L between the Fennder Wheel Arch and Wheel for vehicle and pedestrian safety is 10mm and this design does not meet the requirement.
