Fender Design - Wheel Arch Challenge
FENDER ARCH WHEEL
WHAT IS FENDER- Fender is a BIW part that is not fixed with the body by welding it is assembled with nuts and bolts, Fender is the only part that is a closed component in Clouser another component like the Hood, front door, and rear door, tailgate fuel door can open and close but only fender is only component which we are not able to open like another component.
Fender's primary purpose is its prevent sand mud, and rocks from being sprayed and thrown into the air by the rotating tire.
There are 5 mountings points in fender
1. BODY
2. A-PILLAR
3. SILL
4. COWL
5. DRIP
There are 2 types of fender we used
1.Full bumper type
2.half bumper type
half bumper in present days is widely used
WHEEL ARCH- Whwwl arch is the semi-circular curve on the fender just above the wheel of the car
It has some standard specification , for a vehicle to have its use permit in different countries , the wheel arch of the fender must compliant with the standard set by the respective countries
WHEEL ARCH CALCULATION-Drawing the sketch as per European standards.
CONSTRUCTION OF WHEEL ARCH-
1. First we go to the curve section and select a point in the center of the wheel.
2. Then select Datum plan regarding that point.
3. Select sketch and create a horizontal line through the point (origin)
4. After that we have to create a sketch as per European regulations and finish the sketch.
5 . Project the curve on the surface by using the curve command.
6. before that goes to point option and use intersection option for giving the intersection point to the curve where they intersect each other.
7.Go to analysis command and choose simple distance to measure L value for specified points that satisfy it or not ,as they are as per regulation or not ,if there is some issue then send this report to team for evaluation.
| SECTION | R(should be greater than 5mm) | RESULT | REQUIRED DISTANCE | CALCULATED DISTANCE | RESULT |
| SA |
49.6439MM |
PASS |
10MM | 10.00MM | PASS |
| SB | 32.5497MM | PASS | 10MM | 9.949MM | FAIL |
| SC | 43.3741MM | PASS | 10MM | 5.9018MM | FAIL |
| SD | 48.1377MM | PASS | 10MM | 0.11267MM | FAIL |
| SE | 53.7895MM | PASS | 10MM | 2.468MM | FAIL |
Clearance value at section sa,sb,sc,sd,se are calculated and only at sa section it satisfy or matched as per European regulation.
CONCLUSION
Acooding to European requirement the wheel arch is not good for manufacturing ,so styling team, design team should work on section SB,SC,SD and SE.
