Fender Design - Wheel Arch Challenge
REPORT :
WHEEL ARCH:
Wheel arch is a curved part of the fender positioned risht above the wheel. where it is used to protects the engine compartments , passenger compartment and pedestrian from mud and stones getting inside it . it should be designed inoder to prevent from this . the wheel arch area of the fender is usually designed as a coven or shield over the tyre along its perimetere to prevent muds and stones getting inside the engine compartment. there are different types of regulations for designing the wheel arch depents on different regions. reason for that is diffrence in biw design of cars and maily the road conditions. ithe design should give minimum clearence
EUROPEAN REGULATIONS:
In european regulation as we can see, it requires a predetermined clearence or a minimum distance of 10 mm to be maintanied between the fender . 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 to sc point will also take a mid point.
STEPS FOLLOWED :
*For the calulation of wheel arc i created a datum plane on the top most of the wheel .and i started creatinf a sketch for that a horizontal and vertical line is drawn from the centre of the wheel. the vertical line is SA . after that a line is drawn at an angle of 30deg forward from vertical line SA which is SB . another reference line is created at an angle of 50deg which is SC , which is backward from SA. A horizontal line was created at a distance of 150mm from the centre point . and taken that intersection point in the wheel . which is SE . an another point were created between the SC and SE where it is exaltly the midpoint of the two points . whree its given as SD. after creating the sketch then i measured the distance of 'L' and 'a' . the mesurements are shown below
'L' and 'a' value for section SA
'L' and 'a' values for SB
'L' and 'a' values for SC
'L' and 'a' values for SD
'L' and 'a' values for SE
| SECTION | L>10 MM | RESULT | a> 5mm | RESULT |
| SA-SA | 9.949 | FAIL | 25.99 | PASS |
| SB-SB | 10 | PASS | 44.77 | PASS |
| SC-SC | 0.114 | FAIL | 38.56 | PASS |
| SD-SD | 1.783 | FAIL | 40.95 | PASS |
| SE-SE | 3.59 | FAIL | 43.73 | PASS |
CONCLUSION:
From the above results we can conclude that the fender dose'nt pass the european regulation. as we can see the fender dosent have the clearence of 10mm exept SB section . so the desing of the fender dosent meet up with the requlation
