Wheel Arch Design for Fender Calculation to Satisfied the European and US Standers.

Project objective: In this Project, I am going to find the value of SA, SB, SC, SD, and SE and Calculate of wheel arch for given fender design and validate can it pass European standers and Discus US Standers.

01.About of fender Wheel Arch:

• The wheel arch is the semi-circular part positioned above the wheel of a vehicle. The most important body change was that the front wheel arch was cut higher into the fender. The car has big, high-definition headlights that extend to the wheel arch.

02.About US Stander:

• The Clearances ` L’ at all Position every 10 Degree From -20 Degree to 180 Degree Should Grater than 5 mm to satisfied U.S Regulations.

03.European Regulation Requirement for Wheel Arch:

04.Half Fender wheel Arch As European Stander:

Criteria to pass European Regulation Requirement:

• To satisfy the European Regulations all the sections should have a clearance of 5 mm from the tire when viewed from the top.
• Wheel Guard Requirement- The value of L should be more than 5 mm at a line 30 degree forward and 50 degrees rearward from the central vertical axis of the wheel.​​​​​​​
• The sketch was created on the plane of the tire as per the European Regulations provided. Then these lines were projected on the fender to measure the clearance between the tire and fender.

4.1 Measuring SA:

4.2 Measuring SB:

4.3 Measuring SC:

4.4 Measuring SD:

4.4 Measuring SE:

05.Observation Table:

Sections	Clearance Measured (mm)	Test Result
SA	9.95386	Fail
SB	10	Pass
SC	0.1237	Fail
SD	-3.4356	Fail
SE	-6.9012	Fail

06.Conclusion.

I observed above Calculation of the given fender will not pass European stander in the Position SA, SB, SC, SD, & SE at position SE the required stander is met and further modification at that position is not required. This data will be sent to the styling team for modification in Wheel Arch fender Design.

Thanks & Regards
