Fender Design - Wheel Arch Challenge

AIM:- To decide whether the given design passes the european standard or not.

Given Design:-

European Regulations Requirement:-

1. Take the outline of the wheel and the fender.

2. make the centre of the wheel circle.

3. Draw2 horizontal and verticle prependicular axes the centre of the wheel circle.

4. Draw lines at 30 degree and 50 degree from the centre.

5. make a point on the fender line at 150mm from the horizontal

6. Extend a line this point from the centre

7. Then make a line that is axactly between the 50 - degree line and the line made on the 150mm point.

. Measure the distence between the points on the wheel circle and fender curve all of these should be greater than 10mm to satisfy the european regs

. Secondly, the horizontal distance from SA< SB and SC points to the fender curve should be at least 5mm.

. Check whether the design passes condition and conclude whether it can pass the european regulations requirement

Challenge.

sketch has been made.

Now lets us measure the distance between the points at the 5 section.

SA-SA

25.992 mm>10 mm

SB-SB

43.642 mm> 10 mm

SC-SC

38.36 mm>10mm

SD-SD

41.024 mm>10mm

SE-SE

43.786 mm>10 mm

Now to find the horizontal distace between the wheel and the fender this distace should be at least 5mm from SA point, SB point, and SC point.

Project the made sketch onto the plane of the wheel.

Distance between SA point and fender outer curve = 9.949 mm (pass)

Distance between SB point and fender outer curve = 10mm (pass)

Distance between SC point and fender outer curve = 0,114 mm (fail)

Table:-

Conclusion:-

The given design satisfies all european standard but one, i.e the distance from Sc point to the fender curve (which is just 0.114 mm), which is way below the recommended 5 mm minimum distace . therefore this fender cannot pass the european standard. the design should be reverted back to the class a designer telling him to modify the design and increase the gap there.
