Fender Design - Wheel Arch Challenge

FENDER DESIGN-Wheel Arc Challenge.

AIM :-

To calculate the Fender Wheel Arch area , to pass the European standards.

OBJECTIVE :-

The main purpose of this project is that to calculate the wheel arc area.if car will passed the european market standard or not.because there are different market regulation follows in different countries.

INTRODUCTION :-

Fender is a automoblie part of the vehicle frames .as we know that FR-fender is closing components for the engine campartment .and the major role of fender is to avoid the cipping the engine campartment .during the motion of the wheels tries to pickup sand and mart particles or small stone particles threw inside the car.and FR-FENDER preventing them to hiting the body.and this fender will have a plastic part ,and this plastic part is on the arc area.

These materials can be ejected from the surface of the tire at high velocity as the tire imparts kinetic energy to the attached objects

FENDER WHEEL ARC AREA CALCULATION :-

EUROPEAN REGULATION :-

In the given diagram,the value will be more than 10mm at 30 degree at forward and 50 degree at line above150 mm.

1. Measure the clearance value “L” at Sections SA-SA, SB-SB, SC-SC, SD-SD. SE-SE and ensure the value of “L”.
2. If we pass the Euro regulations, first we need the Clearance (L) value should be greater than the 10mm.

JAPAN REGULATION :-

Here ,we can see that the main objective of the challenge is to test whether the give tire and fender is eligible to qualify with European regulations of Fender design or not.

SKETCH FOR FINDING THE WHEEL ARCH AREA:-

1. A Datum Plane is created at the outermost face of the wheel .
2. The sketch is created on the new Datum Plane.
3. A Horizontal line is drawn across the centre of the wheel.
4. A perpendicular line SA is dropped at the centre of the wheel.
5. A line SE is drawn from the wheel centre and passes from the point created.
6. Project those points on to the fender part.
7. Measure the distance between sketch intersection points and the project point. Then we get the each section.

Section	Clearance	Result
SA	9.94 < 10	Fail
SB	10 >10	Pass
SC	0.11 < 10	Fail
SD	2.9 < 10	Fail
SE	6.0 < 10	Fail

CONCLUSION :-

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