WHEEL ARCH CALCULATION

WHEEL ARCH

OBJECTIVE:

To check whether the given design matches the european standards.

INTRODUCTION:

Wheel arch is room for the wheel in the cavity of body to get it inside. The wheel arch is having some standard according to the region or standards. The main purpose of wheel aarch is to prevent the tiny particles like stones, or dust particles from being hit on the pedestrians.

JAPANESE STANDARD:

The standard of wheel arch should meet the below requirement to pass out the test.

The length of L should be minimum of 5mm. It is the distance between the outer fender and outer most surface of the wheel. A,B and C distance should be more than 5mm, where B is the point at 30 degree angle outwards from the center line,and C is the point at 50 degree angle outwards from the center line.

EUROPEAN STANDARD:

The standard of wheel arch should meet the below requirement to pass out the european test.

In this standard, the length should be more than 10mm, between outer fender and outer surface of the wheel. SB point is at 30 degree angle from the center line. The SC line should be at 50 degree angle from the center line. SE line should be at the meeting point of fender and the line. It should be 150mm above from the center horizontal line. The SD line should at center of SC and SE.

PROCEDURE:

Loading the given design and make the sketch with proper angle, as for european standard and measuring the distance between points.

SB line is drawn and the measurement is 10mm.

The measurement of SA line is 9.973mm

The measurement of SC is 2.965mm

The measurement of SD is 0mm

The measurement of SE is 2.078mm

TABLE:

CONCLUSION:

As SA, SC, SD AND SE measurements are not meeting the requirements, the design have failed the test. The failed points should be changed to meet the requirements .So the design should be sent to previous stage of designing and should be designed as per the requirement.
