Fender Design - Wheel Arch Challenge
FENDER
Fender is the part of a vehicle that surrounds the wheel. Apart from being the exterior aesthetic part of the vehicle, its important function is to prevent debris.such as mud, gravel, rocks, fluids and other street particles from entering the engine compartment or being tossed into the air by the high-speed rotating wheel as this can cause damage to the engine components, nearby vehicles, or pedestrian nearby the moving vehicle.
WHEEL ARC AREA
wheel arc area is an standard regulation one automobile should follow that given by respective country gorvement.wheel arch area is their for the pedestrain safety.when the car is moving some mud,some small sand stones will chipped over the pedestrains ,so wheel arc area is like the offset distance of the fender edge from the tyre it self beacause of these the tyre is inside the fender so the chipping will resist ,depends upon the road conditions different govt gives different wheel arc area.
DIFFERENT WHEEL ARC REGULATIONS
depend up on the climate and road conditions these regulations were put by respective countires in order to the saftey of pedestrains
- Japan wheel arc regulation
- European wheel arc regulation
- American wheel arc regulation
japan wheel arc regulation:-
- Measure the clearance at the given sections with in the area of k and maintain the clearance of 5mm at section A,B,C.
- If the clearance of is less than 5mm at that sections the fender wiol fail the japan regulations.
European wheel arc regulation:-
- Here also we have to measure the clearance at section SB,SA,SC,SD,SE,
- The cleance should be greater than 10mm
American wheel arc regulation:-
- In american regualtions we have calculate clearnce from -10degree to all 180 degree
- and check for the clearmce at all the sections which should be greater than 10mm
We don't want to produce to different fenders for different for same model at different countries then we have to a maximum deviation and check for that value at all the sections.
Checking for the european standards
AT SB POINT
AT SC POINT
AT POINT SE
AT SA
AT POINT SD
| SECTION | REFERENCE CLEARANCE | CALCULATED CLEARNCE | PASSED |
| SA | 10mm | 9.9490mm | NO |
| SB | 10mm | 10mm | YES |
| SC | 10mm | 0.1139mm | NO |
| SD | 10mm | 2.8875mm | NO |
| SE | 10mm | 5.9973mm | NO |
CONCLUSION:-The given design is satisfies the european requirements,so i prefer to redesign it.
