Wheel Arc Calculation Based on US, Japan and EU standards

Wheel Arc Standard calculation based on US, Japan and European Nations

Fender: fender and hood are important components in pedestrian and passenger safety. Fender is where it protects some part of the underbody and passenger compartment by entering the stones, mud water and dust.

Below down the fender, the wheel is mounted and according to the standards according to the European or the japan standards the wheel is placed under the fender at a certain distance.

Wheel arch Distance:

The distance between the fender and the wheel is decided by EU and Japan standards due to the safety of the passengers. When the wheel rotates it tends to lift and throw the stones and dust under the passenger compartment. By this accountable damage will cause to the passenger compartment. The defined distance will reduce the lifting of dust by tyres and damage for the passenger compartment.

Japan Standards: According to the japan standards the distance between the wheel and the fender should be the minimum 5mm distance.

Wheel arc calculation in CATIA v5

in the above image, the distance between the wheel and the arch should be 5mm all around the arch at some sections it fails.

European standards: According to the European standards, the minimum distance between the wheel and the fender should be of 10mm.

American standards: According to the American standards, the minimum distance between the wheel and the fender should be of 10mm.

similarly to the European and japan standards for every 20 degrees, the distance is measured and the distance should be of 10mm clearance
