Fender Design

For the Sill, Bumper, Baffle(Splash), and A-Pillar mount create your own design according to the Engineering standard that you learned. Prepare a report with all the relevant images included for the mounting points created.

What is a car fender?

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

Functional Requirements of Fender:

Most passenger automobiles have four fenders, one over each wheel. For vehicles with a narrow car body that exposes the tire, the fender is an exposed curve over the top of the tire. For wide-body vehicles that cover the tire, the fender forms the wheel well surrounding the tire and is not directly visible from above the car body.

Wheel wells tend to be much larger than the diameter of the tire because they do not move with tire suspension and consequently must be large enough to allow the full range of tire motion on the suspension without touching the interior of the wheel well.

More elaborate designs include fender skirts for enclosing the outside edge of the wheel well, and stylized pontoon fenders for exposed fenders.

When getting into the design we have two types of Fender:

• Full bumper type
• Half bumper type.

Full bumper type

Half bumper type

Presently the conventional methodology is, the basic type that we are using is half bumper type. What is the major reason for going for the half-bumper type. Whenever we use a full bumper type the blank that we used to create this full bumper type is really big and we have quite a lot of wastage around, but in the case of half bumper type, we have a high possibility of reducing the scrap which means by slightly increasing the blank size we can produce fenders at the same time. This is what is called scrap management.

So when we have been given the styling we will be choosing half bumper type because we are reducing the material usage. And that is why people started using half bumper type because every inch of steel or sheet metal is a cost. This will reduce the blank cost drastically so that we provide customers with a better fender for a cheaper price. This methodology will allow us to use a lot of plastics on the bumper which means you are reducing some particular proportion of steel's weight. When we particularly reduce the proportion of steel weight, we also increase the performance of the vehicle. This is also one of the favorable decisions that we make to reduce weight. That is why we started using the half-bumper type.

Mounting:

There are 5 mounting points in a Fender

They are:

• Body
• A-Pillar
• Sill
• Cowl
• Drip
• Splash /baffle
