Fender Design - Wheel Arch Challenge

Calculate the Wheel Arch gap at required points and check whether the car passes the European standard.

Aim:- Calculate the wheel arc gap at the required points and check whether the car passes the European standard or not.

Theory:-

1. About Fender

The fender is a sheet metal part of an automobile. It Plays a vital role in the automobile industry. This is one type of covering which covers the engine department from the side and works as a shelter for the wheels. Its main function is to prevent the passenger which is inside the car while rotating the wheel wheels threw the mud, sand, and some tiny particles this time this fender is working as a shelter that protects and restricts the mud, sands, and some other particles to go inside the car and in the engine department. 

2. About Wheel Arch 

It is a curved part of the Fender positioned right above the Wheel. The Wheel Arch is designed such that it protects both the pedestrian and car cabin from mud, water rocks, and other road sprays. Different countries have different wheel arch standards like that we have seen in the video Japan has its own wheel arch regulations, the US has its own wheel arch regulations and European has its own standard for the wheel arch regulations.

As in this challenge, the wheel has to cross-check the values of the fender which is given to us according to the European Standards. This mainly tells us what gap should be taken for at the time of designing the fender, and is the dimensions is satisfying the design rules and customers' demands.

So in the following diagrams, we have seen the different values for JAPAN, the US, and EUROPEAN. Out of these three, we have to check for European standards.

Wheel Arch Regulations for 

1. Japan
2. US
3. European

Sketch

For Side Line which is inclined at 30 degrees from the center line

Clearance of this line BB-10 mm

For Side Line which is inclined at 50 degrees from the center line

Clearance of this line CC 2.0241*10^-6 mm

For central line itself 

Clearance of line AA-9.9402 mm

For the line Which is the point at 150 mm

Clearance of line DD 0.0002 mm

Midline of 150mm line 

Clearance of line EE-3.170 mm 

Measuring the clearance vlaue'a' for Wheel Guard Requirement

a=45.3786 mm

a=37.0599 mm

CONCLUSION

From the above results, we can conclude that the Fender does not pass the European Regulations, as the minimum clearance L between the Fender Wheel Arch and Wheel for vehicle and pedestrian safety is 10mm and this design does not meet the requirement.

SECTION	LENGTH > ( 10 mm )	RESULT	a> (5 mm)	RESULT
BB	10 mm	PASS	45.3786 mm	PASS
CC	2.0241*10^-6 mm	FAIL	37.0599 mm	PASS
AA	9.9402 mm	PASS
DD	0.0002 mm	FAIL
EE	3.170 mm	FAIL
