Fender Design - Wheel Arch Challenge

Wheel Arc

Objective

To calculate the wheel arc Gap and Check wheter it passes the european standard

What is a wheel Arc

The wheel arch is an arch shaped cavity in the fender. the main purpose of the cavity is to proctect the pedestrian from flying debry, when the ar is in motion.

For this calculation we have most comman three Standards around the world

1. Japan Standard

2. American Standard

3. European Standard

For this Wheel arch we are using European Standard

Step 1

Create a datum plane on the outer most surface of wheel

Step 2

Create a skecth on that datum plane according to european std shown above

and create points on the intersection of wheel arc and wheel

Step 3

Project the points on fender and Calculate the distance btween them. This value is called the L value Tolerance

It should be 10mm or more than 10 mm

Step 4

Calculate the distance btween points on wheel and fender the A Vaule and the value should be 5 mm or more

Section A-Value (mm) Pass L-Value (mm) Pass

SB 49 Yes 10 Yes

SA 32 Yes 9.98 No

SC 42 Yes -0.11 No

SD 47 Yes -2.87 No

SE 42 Yes -5.99 No

Conclusion

As per the Europen std the wheel arch best fit in A-Vaule

but not in L-vaule.

So this will not pass the test

Tip-Try reducing the curvature of fender
