Fender Design - Wheel Arch Challenge

                                                 REPORT:

OBJECTIVE:

        To study the standard and the regulation for the fender design of wheel arch area and then analysis the data which is given in the question whether the wheel arch area will going to pass the standards or not.

        There is various standard which normally varies by region and there road structure like japanese, u.s AND europe, here  we are going to take european standard.

INTRODUCTION TO FENDER:   

        1.Fender is the American English term for the of an automobile, motorcycle or other vechicle boy that frames a wheel well (the fender underside). its primary purpose is to prevent  sand, mud, rocks, liquides, and other road spray from being thrown into the air by the rotating tire.

        2.Which is also used to protect the sides of the engine compartment.

        3.The fender also prevents the predestrian injury when there is a predestrian vechicle collision and also its prevent throwing up of  debries to nearby vechicles.

        4.commonly The front fender is designed seperatly, The rear fender come along with the vechicle structure.

        5. pedestrain saftey is also considered while designing wheel arch in the fender since the debris in the wheel should hit them in the motion of the car

TYPES OF FENDER:

  1) Full-bumper type: This is a conventional type used in fender and This fender covers almost 75 percentage and its shown in image.

2) Half bumper type: This type of bumper mostly helps in reducing the weight of fender at the same time it is improves a lot for saftey of the predestrain moving . This type of image is shown below.

FENDER DESIGN CONSIDERATIONS:

1.Drip area

2. wheel arch

3. Baffle and ORVM mounting area

4.frontal crash regulation and its requirements

Designing Standards for front fender:

   European standard for wheel arch: According to the  european standard clearance length for the wheel arch will be 10 mm

   Wheel CTR is also know as wheel center. SA,SB,SC,SD,SE are the points on the wheel from were it is projected to the wheel arch to measure the distance.

RESULTS:

    REGION                   MEASURED VALUES        QUALIFIED OR NOT

       SA                           9.9490                                  NO

       SB                            10                                       YES

       SC                           - 0.1139                                 NO

       SD                            -2.8875                                 NO

       SE                            - 5.9973                                 NO

 CONCLUSION:

The wheel arch distance is measured and checked whether it will meet the european standard.The results shows that the car will not pass the european standard since the only SB region meets the requirements.

The model will be sent to the styling department for reconsidering the wheel arch on the stylished fender.
