Fender Design - Wheel Arch Challenge

WHEEL ARCH CHALLENGE

OBJECTIVE: The objective of the wheel arch challenge is to calculate the wheel arch area and to prove the given fender of car will pass the European standards or not.

1. Wheel arch:

Wheel arch is the semi-circular part of the fender positioned above the wheel of the vehicle.

The most important body change was that the front wheel arch was cut higherinto the fender.corrosion had around the splash plate at the back of the wheel arch.

The design wheel arch of a fender should be such that it must shield wheels and protect both passenger's compartment with the standards and regulations set by the respective countries.

Take outline of the wheel or fender

make a line with 30degree and 50 degree and make point of the horizontal length of the 150 mm

Measure the distances between the points on the wheel circle and fender curve. all are should be greater than 10mm.

secondly the horizontal distace from SA, SB, SC.

whether the design passes these conditions and conclude whether it can pass the european standards

SKETCH REQUIRED:-

SA-SA:-

26MM >10MM

SB-SB:-

43.6MM>10MM

SC-SC:-

38.4MM>10MM

SD-SD:-

41.00MM>10MM

SE-SE:-

43.8MM>10MM

NOW WE HAVE TO FIND THE HORIZONTAL DISTANCE BETWEEN THE WHEEL AND THE FENDER THE DISTANCE SHOULD BE ATLEAST 5MM FROM THE POINT SA, SB, SC.

DISTANCE BETWEEN POINT SA AND FENDER OUTER CURVE = 10MM

DISTANCE BETWEEN POINT SB AND FENDER OUTER CURVE = 10MM

DISTANCE BETWEEN POINT SC AND FENDER OUTER CURVE = 2.4MM

SA-SA 26MM > 10MM OK

SB-SB 43.6 MM > 10MM OK

SC-SC 38.4MM > 10MM OK

SD-SD 41MM > 10MM OK

SE-SE 43.8 MM > 10MM OK

DISTANCE BETWEEN THE WHEEL TO THE FENDER OUTER CURVE

SA 10MM > 5MM PASS

SB 10MM > 5MM PASS

SC 2.4MM < 5MM FAIL

CONCLUSION:-

The given design does not satisfies all the european standards distance from point sc to the fender curve which is 2.4mm that is why below the recommended 5mm minimum distance therefore this fender cannot pass the european standards the design should be reverted back to the class A designer to modify the design and increase the gap.
