Fender Design Challenge

Design of Fender

Objective: To design various mounting points on the fender, according to the design parameters.

Software Used: NX CAD 12

Introduction: Fender is the part of an automobile 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.

Types of Fender

• Full Bumper Type
• Half Bumper Type

Fender is mounted basically on five important regions:

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

Given data:

Design Procedure:

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.

• Drip Area

A-Pillar Mounting Area

Sill Mounting Area

Bumper Mounting Area

Baffle Mounting Area

Conclusion

In this challenge i learnt how to design the Fender Mountings using Nx CAD 12 considering all the design parameters.
