Fender Design - Wheel Arch Challenge

Objective:

Calculate the Wheel Arch gap at required points and check whether the car passes the European standard.

Wheel Arch

• The design of the wheel arch of a fender should be such that it must have shield wheels and protect both passengers compartment and pedestrians from the projection of Water, Mud, and Stones.
• Wheel Arch is the Semi-Circular part of the fender positioned above the wheel of the vehicle.
• For the vehicle to has its use permit in different countries the wheel arch of enders must be compliant with the standards and regulations set by the respective countries

Wheel Arch Regulation

• Regulation vary in the car used in the region or country.
• Japan,Europe and US country are use the separate regulation standards.

European Regulation Standard Values

The car wheel extreme outside and fender wheel arch area distance is should be more than 10 mm is satisfy.

• 'a' value is more tha 5mm in SB and SC region.
• 'L' value is should be greater than 10 mm

Conclusion

• The given car fender is not satify the european standard so this car not pass the european standard.
• The wheel arch gap 'L' value is less than 10 mm in 4 region.
• Wheel arch gap 'a' value only satisfy the regulation standards.
