Fender Design Challenge

FR-FENDER

Object :- To design the fender from given skin data and master section provided with Drip mounting, A-pillar, Sill mounting, Cowl mounting, and Splash mounting.

Introduction :- Fender is the side engine closing part. This is used to cover the engine from side. It’s also advantage that avoids chipping towards engine compartment. And it prevents the pedestrian from chipping injuries. If fender is designed in a good way according to keeping in mind the design of vehicle then the beauty if car increases.

               Fender have two types-

1. Full Bumper Type Fender
2. Half Bumper Type Fender

Full Bumper Type Fender :-

          In this fender it covers full wheel arch area. But in this, sheet consumption is more and sheet wasting is more. Because of this its prices increases.

Half Bumper Type Fender :-

          In this fender, it does not cover full wheel arch area. It covers partial wheel arch area, and remaining wheel arch area is covered by other part like bumper. Its benefit is that it takes less sheet consumption and less sheet wasting compare to full bumper type fender.

FR-Fender are designed keeping many things in mind….

1. Design requirements for fender and its components.
2. Functional Requirement
3. Important Regulation
4. Drip Area
5. Wheel Arch
6. Baffle and ORVM mount area
7. Frontal crash regulation and requirements
8. GAP and flushness requirements

There are five mounting point in FR-Fender.

1. Bumper Mounting
2. A-pillar Mounting
3. Sill Mounting
4. Cowl Mounting
5. Drip Mounting

1.Bumper Mounting :- This mounting would have been tight towards the bumper.

2. A-pillar Mounting :- The mounting that is mounted vertically on the back edge of the fender. That is called A-pillar Mounting.

3. Sill Mounting :- The mounting that is mounted horizontally down the back side of the fender. That is called Sill Mounting.

4. Cowl Mounting :- The mounting of the fender that seems to be tight near the dashboard, is called Cowl mounting.

5. Drip Mounting :- The mounting of fender that mounts to the engine side, is called Drip mounting. The vertical length of the drip is not more than 40mm. And horizontally it should be minimum 10mm gap between drip edge and engine. To protect it from spring back, Dart is added in it according to the below figure.

Design Consideration :-

           In this, with the help of skin data and master section which is provided, it is designed. In this design the tool that were used where need such as surface on curve, bridge curve, law extension, emboss, face blend, edge blend, projective curve, trim sheet, dart etc. according to the below figure.

Conclusion :- In this project we learnt that how to design the FR-Fender with keeping in mind about easy way manufacturing process like emboss.
