Fender Design - Wheel Arch Challenge

FENDER WHEEL ARCH CHALLENGE

FENDER WHEEL ARCH. Wheel Arch is trhe semi circular part of the fender positioned above the wheel of the vechcle. The design of the wheel arch of the fender should be such that it must shield wheels and protect both passengers compartment and pedestarians from the projection of watr, mud and stones.

Fender is the side closing component for the engine compartment. It’s major role is to avoid chipping sand, small stones and mud particles inside the engine compartment when the wheels rotate. Fender also plays a major role to prevent injuries for the pedestrians. Basically we have two types of fender half bumper type and the full bumper type. The difference between two types are its size. The raw material usage plays a major role and so half bumper is economical.Drip area and wheel arch are one of the two important things to be considered while designing fender.

Wheel Arch:

There are standards all over the world for wheel arch of a car. Country to country they will fix a certain regulation considering the infrastructure available in their country. Basically when the wheel is seen from the front side and if it was outside the car the chipping will be more and that causes damage to the engine compartment and the pedestrians.

European Regulation:

As like Japan it also says to draw two line with wheel centre point and reference to vertical line on the wheel with 30o on the left and 50o on the right. Projecting the points to the wheel arch the points must be 10mm or above. And additionally we will have to take a 150mm point from the zero or horizontal line of the wheel and also in between the 150mm point and the 50o point we will also take a midpoint. Along with this we need to measure “a” the distance between the outer most layer and the SB, SC should be above 5mm.distance between arch and tyer should be 10mm distsnce maintain

procedure;

create a plane and cerate a skech on that plane create the lines and point as per europian standards

measuring the distance between fender arch points and taking wheel edge lines

check all points and consider its under the standard

europian standars takes 4 points at verifaying .

in this design visually its not ok because the tyers oustside of fender wheel arch from taking ponits

CONCULSION

SL NO	SECTIONS	DISTANCE	RESULT
1	SB	10mm	pass
2	SC	0.125mm	fail
3	SD	2.9344mm	fail
4	SE	6.0891mm	fail

in this fender wheel arch design not maintain the eupropian standarad dimensions so its not ok
