Fender Design

FENDER DESIGN

AIM: To design a front fender of a car by following the given master section as per the design considerations of OEM.

FENDER: A fender is the curved portion of the car's body that sits over and houses the wheels.

What Is The Purpose Of A Fender On A Car?

The purpose of a fender is pretty simple. Its purpose is to keep mud, rocks, and other road debris from being thrown around by the tires. In other words, the fender is a housing for the wheels that keeps road debris contained. If there was nothing covering the wheels, all kinds of debris would be kicked up by the rotating tires.

The fender not only protects your car from sustaining damage from road debris but it prevents this debris from being thrown up at other vehicles on the road. This is why vehicles with large, oversized tires are often required by law to install fender flares.

TYPES OF FENDER:

The type of fender is based upon the area covered

1. Full fender type
2. Half fender type.

• Presently we are using the half bumper type , the reason for choosing the half bumper type is that when we choose the full bumper type the blank used for creating it is very large and also has the lot of wastage , but in the case of the half bumper type we have the possibility to reduce the scrap . This is what we called as scrap management
• In half bumper type we reduce the usage of the steel material and uses the lots of plastic on the bumper which in term decreases the cars weight and increases the performance.

DESIGN CONSIDERATIONS

The front fender has basically five mounting positions with respect to the other components. The mounting positions are as follows:

1. Drip Area Mounting.
2. A-Pillar Mounting.
3. Sill Mounting.
4. Bumper Mounting.
5. Baffle Mounting.

MOUNTING REGIONS ON FENDER :

For the creation of the Drip Area Mounting, the given Master Section is followed, and the other mounting points are created by assuming appropriate positions with the respected components.

1] Drip Area Mounting:

• The drip area is the most important mounting in a fender, it is the point where the fender has to be attached to the engine compartment.
• The drip area should be designed in such a way that it should be at least 150mm away from the front end of the fender to have sufficient space for mounting headlamps housing.
• Mostly the drip area starts from 200mm away from the rear end of the fender, to have sufficient space for the cowl which carries the wiper equipment.
• The length of the drip area depends on the length of the fender.

2] A-Pillar Mounting:

• This mounting position is created for attaching the fender to A Pillar of the vehicle.
• The mounting has to be created by taking the reference from the A-pillar of the vehicle.
• Enough clearance should be given for the easy mounting of the wiper equipment.

3] Sill Mounting: Sill mounting is created on the bottom portion of the fender for attaching to the sill.

4] Bumper Mounting: This mounting point is created for attaching the bumper to the fender. It should have enough strength to hold the bumper steadily.

5] Baffle Mounting: These mounting points are created for attaching plastic components i.e baffle which prevents chipping inside the engine compartment.

DIFFERENT VIEWS OF FENDER:-

CONCLUSION: Thus, all mounting areas for the fender designed from skin data and master section is done by following all design rules.
