Fender Design

Fender Design

Aim:

To design a Fender by using given design parameters and explain about design, different mounts and manufacturing process.

Fender:

Fender is one of the BIW in automobile, which is the part that covers a wheel, engine compartment and the pedestrian from sand, mud, rocks, stone and liquid spray by the rotating tyre. And also Fender is the safety frame for protect the tyre.

There are two types of fender,they

1. Full bumper type

2. Half Bumber

In nowadays, mostly conventional type car and basic type cars using half bumper types only, because of slightly changing the styling and reduce the weight of BIW. Half bumper is also one of the weight reducing technology.

Fender Manufacturing Process:

Embossing

Embossing is the process to stamp the sheet metal and produce the required shapes. The fender design some pressure induced to the sheet metal and deformation takes place in sheet metals , get required geometrical shapes. After that we use some drill tools to make holes.

Bending:

Bending is the common sheet metal manufacturing method, applying a force to one direction and bend to required sides. Mainly create a curvature surfaces in sheet metal.

Cutting and Drilling:

It is also common sheet metal fabrication process, cutting is to remove unwanted and sharp area of fender and the drilling is placing the fasteners to the fender area.

Fender Design:

In fender design we should be consider 5 mounting points. They are

1. Baffle
2. A Pillar
3. Sill
4. Cowl
5. Drip

Baffle Mount:

The Baffle mount is the fender to mount the body area has particular mounts, and its attached to the body with fasteners. It is protects the engine compartment and pedestrians from the debris and liquids.

A-Pillar Mount:

A-Pillar mount is structural reinforcement to attached roof and back strengthen to the wind shield.

Sill Mounting

Sill is the under part of fender and its attached to bottom of the door and may be combined to the floor of doors.

Cowl Mounting

Cowl is mounting to the roof attachment and has some plastics, wiper motor spacing.

Drip Mounting

Drip area is one of the most important mount attached to the engine compartments by using fasteners. In design Drip area should be consider the rear end of fender need to leave at least 200mm for cowl top part. Front end of fender area leave at least 150 mm for head lamp and housing unit.

Design Parameters:

Final Design

Conclusion

I learned Design of fender successfully with the help of NX-CAD software by the given master section.
