Fender Design Challenge

FENDER DESIGN

1. FENDER

Fender is the US English term for part of an automobile (vehicle body of car) that frames the wheel well (the fender underside). Its main purpose is to shield wheels and protect both passenger’s compartment and pedestrians from projection of water, mud and stones.

Fender is one of the styling components which is exposed to customers from which cannot be welded. Most of the assembly joining is done using fasteners, retailer clip and proper fitting.

Fenders are either made of steels or thermoplastics.

Property of Steel vs Plastics

Types of Fenders:

1. Full Bumper Type

This kind of fender was used in the late 80’s car, as fenders are generally used to protect from the dust, stones and mud being deposited on the car. But this type of fender takes more material compared to the Half fender Type ie. Two half bumper type fender can be manufactured from one full bumper type fender.

1. Half Bumper Type:

This is the new convention model fender used in the current era among the car manufactures since it reduces the weight and the cost constrains.

Fender Point Mountings:

1. Drip Area
2. Bumper Mounting
3. Splash Cover / Wheel Well
4. Sill Mounting
5. Body Mounting

Design Data Provided:

Design Considerations:

1. Embosses are provided to increase the strength
2. The corners flanges are smoothened to ease the productivity of the part
3. Fillet of 2-3mm is provided to avoid sharp corners and edges.
4. Uniform wall thickness of 0.75 mm is maintained.
5. The wheels that are outside the fender are more prone to Chipping than the wheels that are located inside the fender. Hence the wheels that are inside the fender are mostly preferred.
6. Darts are provided on some areas to improve the stiffness of the mountings to avoid NVH issues.

Design of Bumper:

The main objective of this is to design the Drip Area, Body Mounting, Bumper Mounting, Sill Mounting and Splash cover / Wheel Well.

• Drip Area Mounting:

• Bumper Mounting:

• Sill Mounting

• Splash Cover / Wheel Well

• Body Mounting and A - Pillar Mounting

• Slot for Mounting Turn Signal Light:

Conclusion:

Thus the Designing of the Fender design is completed using NX CAD considering all the design parameters and considerations.
