Fender Design - Wheel Arch Challenge

Fender Design - Wheel Arch Challenge

Scope:

To Calculate t0he Wheel Arch gap from the given design part and check whether the car passes the European standard or not.

Fender:

Fender is one of the BIW automobile part that protect the wheel, engine compartment and the pedestrian from sand, mud, rocks, stone and liquid spray by the rotating tyre. And also Fender is the safety frame for protect the tyer.

Fender Wheel Arch:

In this challenge we are going to propose the European standard, the given wheel arch design as shown in Figure.

For European standard, We mark the vertical line(B) from the wheel origin, and then mark 30° (A) from vertical line in (-XY axis) and 50° (C) in xy axis. Another line(E) from the origin to the wheel arc which is 150mm from the zero level.And one more line (D) which is bisecting between line Cand E .

Wheel Arch Gab Measurment:

All the region the gab between the wheel arch and the wheel clearnce must have some values. In european standard the wheel should be inside the wheel arch and the clearance is 10 mm.

Analysis: Line A

The gab between the wheel face and the wheel arch is 10 mm.

Analysis: Line B

The gab between the wheel face and the wheel arch is 9.9490 mm.

Analysis: Line C

The gab between the wheel face and the wheel arch is -0.113949 mm. (-minus sign refers reverse direction that means the wheel comes outside the arch)

Analysis: Line D

The gab between the wheel face and the wheel arch is -2.8875 mm.

Analysis: Line E

The gab between the wheel face and the wheel arch is -5.9973 mm.

Observation

The minus (-) sign denoted by the reverse direction only not a value.

Conclusion:

From the above analysis, in this wheel arch design the wheel in line C,D,E is slightly outside from the wheel arch. And the Line B is not meet the European standard, only the line A is satisfied the European standard. So the design team need to modify the clearance more than 10 mm which is satisfy the European standard.
