Fender Design - Wheel Arch
FENDER DESIGN – WHEEL ARCH
OBJECTIVE OF THE WHEEL ARCH:
Main objective of the project is to calculate the Wheel arch area, and also conclude, If the car will pass the European standards or not. Because of countries are follow the different regulation.
WHEEL ARCH:
Wheel arch is the semi - circular part of the vehicle is position on the top of the wheel. Wheel arch claddings are there to stop water and dirt ingress from getting into tight spots around the wings of the car to prevent corrosion.
They also protect any electrics or pipework from the water. They are originally made for vehicles when are supposed to take more abuse in terms of off road or water wading. It prevents scraping of paint near wheel arches also prevents water from getting inside the panel which could lead to rust.
Wheel arch is must be shielded the wheel, because it will ensure that passengers and pedestrian are not affect by the stones, mud, water from the bottom of the car.
EUROPIAN STANDARDS FOR WHEEL ARCH:
- Measure the clearance value “L” at Sections SA-SA, SB-SB, SC-SC, SD-SD. SE-SE and ensure the value of “L”.
- If we pass the Euro regulations, first we need the Clearance (L) value should be greater than the 10mm.
SKETCH FOR FINDING THE WHEEL ARCH AREA:
If we need to finding the Wheel arch area, then we have sketch on the tire surface.
CLEARANCE VALUE (L):
After creating the sketch, you will use the law extension feature in NX Cad. Then Finding the Clearance value between the Fender edge to law of extension edge
Let, find the value pf “L” at the sections SA-SA, SB-SB, SC-SC, SD-SD, SE-SE.
1.MEASURING THE CLEANRANCE (L) VALUE AT SECTON SA-SA:
As shown in the picture, clearance value between the Section SA-SA. The minimum clearance value is 10mm, but the section SA-SA clearance value is less than 10mm.
2.MEASURING THE CLEANRANCE (L) VALUE AT SECTON SB-SB:
As shown in the picture, clearance value between the Section SB-SB. The minimum clearance value is 10mm. The section SB-SB clearance value is equal to the 10mm.
3.MEASURING THE CLEANRANCE (L) VALUE AT SECTON SC-SC:
As shown in the picture, clearance value between the Section SC-SC. The minimum clearance value is 10mm. but, the section SC-SC clearance value is outside direction of 0.113mm. The tire is outside of the car. so, aesthetic look of the car bad as well as it is danger for pedestrian safety.
4.MEASURING THE CLEANRANCE (L) VALUE AT SECTON SD-SD:
As shown in the picture, clearance value between the Section SD-SD. The minimum clearance value is 10mm. but, the section SD-SD clearance value is outside direction of 4.941mm. The tire is outside of the car. so, aesthetic look of the car bad as well as it is danger for pedestrian safety.
5.MEASURING THE CLEANRANCE (L) VALUE AT SECTON SE-SE:
As shown in the picture, clearance value between the Section SE-SE. The minimum clearance value is 10mm. but, the section SE-SE clearance value is outside direction of 10.808mm. The tire is outside of the car. so, aesthetic look of the car bad as well as it is danger for pedestrian safety.
TABLE A:
From the table A, the given fender doesn’t pass the European Regulation for wheel arch area at SA, SC, SD, SE sections.
WHEEL ARCH AREA FOR GIVEN FENDER:
So, the given fender Wheel Arch area is 24432.933mm2
Wheel arch length is 104.512mm
CONCLUSION:
The given fender is Fail the European Regulation for Wheel Arch Area. Because of clearance value is varies between the section to section. Due to the Tire is Go outside direction. So, it is danger for pedestrian safety as well as aesthetic look of the car also bad.
