Fender Design Challenge
DESIGN OF CAR FENDER AND MOUNTING STRUCTURES
FENDER:
Fender is the American english term for the part of an automobile, motorcycle or other vehicle body that frames a wheel well (the fender underside). Its primary purpose is to prevent sand, mud, rocks, liquids, and other road spray from being thrown into the air by the rotating tire. Fenders are typically rigid and can be damaged by contact with the road surface.
More elaborate designs include fender skins for enclosing the outside edge of the wheel well, and stylized pontoon fenders for exposed fenders.
Sticky materials, such as mud, may adhere to the smooth outer tire surface, while smooth loose objects, such as stones, can become temporarily embedded in the tread grooves as the tire rolls over the ground. These materials can be ejected from the surface of the tire at high velocity as the tire imparts kinetic energy to the attached objects. For a vehicle moving forward, the top of the tire is rotating upward and forward, and can throw objects into the air at other vehicles or pedestrians in front of the vehicle.
Need of Fender:
- It is designed to provide resistance against wind, muds, and roadside particals.
- It is the sheet of metal covering of the car.
- Fender has a plastic part called Baffle or fender Liner which fits underside the fender to protect the metal from corrosion by stopping the flow of mud and water inside from different road conditions.

There are 2 types of fenders.
- Full Bumper Type
- Half Bumper Type
Full Bumper Type: Full Bumper Type is not used now a days because it requires large size of balnk to produce the part and it occupies more space.
Half Bumper Type: Half Bumper Type Half bumper is used because the waste of material is less & can produce two fender at the same time by slightly increase the raw sheet. and to reduce the weight & cost mostly bumper fender are been produced.

Fender Mountings:
Fender has several mountings which are used to connect with bumper, A-Pillar, Sill, Cowl, Drip.
Given Master Section:

The above Image is the Given Master section used to Design Fender and Mounts which are listed above.
Drip Mount:

The above image is Drip area mount used to connect with BIW Part of Engine Compartments. We need to follow the standard design consideration which could be followed by any OEM. The length of Drip Mount is Varied between the OEM. We know that the Drip mount is connected with the Engine Compartment with some Fastening technique.
A-Pillar Mount:

This mount is designed in such a way to connect with A-Pillar of car Side body.
Sill Mount:

Sill is a part of Upper body structure of BIW of car. Car door sill is a small strip of metal placed at the base of your doors. These plates offer support, protecting your car's frame to ensure there's no sagging. Sills also provide a solid footing, allowing you to climb in and out of your vehicle comfortably.
Bumper Mount:

This mount is used to connect the Bumper of the car.
Baffle Mount:

This Mount is used to install the Baffle, baffle is a sponge type material which is installed above the wheel arch to fender. Baffle is installed to reduce the noise and vibration developed during running the vehicle.
