Fender Design - Wheel Arch Challenge
WHEEL ARCH CALCULATION:
AIM:
To calculate the wheel arch gap at required points and check whether the car passes the European standard for given part model.
INTRODUCTION:
FENDER:
- Fender is the sheet metal part is used to avoid chiping inside the engine compartments like stone water etc...
- It had a plastic part part placed in arc area
- it is define into full bumper type and half bumper type
- full bumper had bigger in size and lot of waste area is there
- half bumber type recently used technology that had good aesthetic ,lesser amount of material and lesser in cost also.
- it had five mounting region that are,
- Body
- A pillar
- Sill
- Cowl
- Drip

wheel arch area:
- It is plastic part that mount with front fender part to avoid the chiping and protect a car fender inner side and pedestrian safety.
- It had some standard specification.
1)Japanish Standard
As per the Japan Standard, the Clearence value L i.e. the gap between the tyre and the fender wheel arch should not be less than 5 mm for all the 3 points B, A & C.
2)American standard:
Lines are drawn from the centre of the wheel for every 10 degrees, from -20 to 180 deg as shown in the given below figure, So as per American standard the clearence gap distance between the wheel and the fender wheel arch should not be less than 5 mm at every 10 degree angle.
European standard:
- We will do the European standard experiment on given part file.
- As European standard the projection point should be maintain 10mm gap between top view and front view of the wheel arch area.
- In above mentioned picture there is SB,SA,SC,SD and SE points are should be maintained with in 10mm to top view of the wheel arc area
- for give part file had projection of given below figure

FOR SB:

- It was passes the European standard,Because here comes 10mm
FOR SA:

- It was almost passes the european standards,because here distance comes 9.97mm,0.03mm is negligable
FOR SC:

- For SC It was not pass,because the value comes 2.93mm only.
FOR SD:

It was not pass,becauce its value is 0.228mm.
FOR SE:

- This point also not pass because the value is 3.1557mm
Conclusion:
| POINTS | VALUES UPTAINED | RESULT FOR EUROPEAN STD |
| SA | 9.97mm | ALMOST PASS |
| SB | 10.0mm | PASS |
| SC | 2.93mm | FAIL |
| SD | 0.22mm | FAIL |
| SE | 3.15mm | FAIL |
