AIM:

The aim of these project is to design fender and the main design requirements for Drip area, Bumper, A pillar and Sill mounting areas.

Outer of car :

Designing of Front Fender and Mounting areas : Skill-Lync

Fender :

            Fender is a front outer side member of a car which covers the wheel side. Fender purpose is to prevent sand, mud, rocks, liquids and other particles. 

Genuine Fender for 2008-2011 Saab 9-3 | Part# 12769230 | Over 30% Off All  Genuine Saab Parts & Accessories | Saab Parts Counter

            Fender is a closure component, closing the engine compartment and other compartments. The major role of the fender is to avoid the chipping inside the engine compartment. During the motion the wheel picks a sand mud and small stone particles and throws it inside the car and these fenders will be helpful in preventing them by hitting inside the engine compartment and car body. These fenders will have a plastic part which lies on wheel arch area. The fender plays a major role to avoid problems for pedestrian also.Fender are typically rigid and can be damaged by contact with the road surface. It is often also called as Mudguard.

Types of fender :

  • Full Bumper Type.
  • Half Bumper Type.

Full Bumper type :

       It is not used now a days because they requires bigger size blank to produce the part and the large scrap is also produced.

 

Fender Design Challenge : Skill-Lync

 

Half Bumper Type :

Half bumper types are used in present and future also because the blank size is less and the wastage or scrap is less comparing to full bumper type fenders.

Uses of car Fenders :

  • Car Fender limit the exposure of your car's body and engine to external elements that are harmful.
  • Fender flares are attached to ensure that both the body and engine have minimal contact with corrosive elements
  • Car Fenders provides safety to the driver and the passengers at the time of accidents or collisions. They are manufactured in a way to provide bend during front and side collisions.
  • Car Fenders are designed to avoid wind resistance and make your car more aerodynamic.
  • Car Fender enhance the overall look of your cars. Fender flares are available in distinctive designs in the market. Mostly you find universal Fender flares, but you can get customized cars Fenders to fit your car wheels.

Areas to be considered while designing a fender :

  1. Drip area
  2. Bumper mounting area
  3. Sill mounting area
  4. A pillar mounting area

 Fender Design Challenge : Skill-Lync

Drip area :

             Drip area mounting is the important part in the fender . this mounting is attached to the engine compartment of the car . fender drip area is mounted via weldnuts to the engine compartment .a min of 150mm distance is kept from the front side and a distance 300mm or less can be kept on the rear side . the total length of drip area from the top of fender should be less than 40mm , this is to avoid the springback during the manufacturing . the edge of the mounting should atleast 10mm away from any nearby component in the engine . a rigidity bead is provided at the end to increase the strength of the mounting .

Bumper mounting area :

             Sometimes fender is also provided with the cowl area mounting . this mounting is on the top side of the fender .

A-pillar  mounting area :

             The A-pillar area mounting depends upon the A-pillar of the car . the mounting can also be provided with ribs to strengthen the part . this mounting is critical in design as it has to be mounted on A-pillar properly.

Sill mounting  area :

             Sill area mounting is also an important mounting part .this mounting point is basically on the bottom of the fender . the mounting part should be created such that the fender is firmly attached to the sill .

 

FENDER DESIGN:

 

GIVEN FENDER SURFACE:

The side faces of the fender is splitted to create mouting surface, to create flanges in drip area,sill mounting,A Pillar , bumber and wheel arch area.

Steps done to create the mounting flanges :

  • Boundary
  • Parallel curve
  • Points
  • Spline
  • Join 
  • Split

 

MASTER SECTION FOR DRIP AREA:

 Fender Drip Area Section

Considering the above design constrains we have to design the drip area. Embosses are provided to increase strength, corners of the flanges are smoothen to ease of the production. Uniform wall thickness of 0.75mm.

  • Design Consideration for drip area are150mm distance from front end of the fender and the gap is filled with headlamp 200mm distance from rear end of the fender and the gap is filled with wiper motor assembly.
  • Initially 3-degree angle and 9mm length is given while creating a drip area because the engine component should not be visible from outside.
  • The depth of the drift should be between 40 to 60mm. If the depth exceeds from 60mm then forming is not feasible due to spring back and wrinkles.
