Fender Design Challenge

Aim:

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

Fender:

A fender is a part of an automobile that frames a wheel well (Fender underside). Its primary purpose is to prevent sand, mud, rocks, liquids, and other road sprays from being thrown into the air by the rotating tire. The fender's openings for the wheel wells tend to be much larger than the diameter of the tire because they do not move with the tire suspension and consequently must be large enough to allow the full range of tire motion on the suspension without touching the interior of the wheel well.

Types of Fender:

Full front fender:

If the fender covers the tire, the wheel well surrounding the tire, and it is not directly visible from above the car body. It increases the weight and scrap of the component.

Half front fender:

It reduces the weight and scrap. It creates only half of what the full front fender does and the other part is created with the bumper part.

Procedure:

1. Creating the sections:

• After Opening the File, Check the model and create the mount area layouts.
• Use parallel curve option to offset the line to 5mm and split option cut the class A to create a space for the mountings.
• Now, join the split surface excluding the top surface.

2. Creating the Mount part:

• To create the mount regions, use the sweep option near the space created for the mountings.
• After the sweep is done as per the design model given, join the surface created.

3. Creating the embosses and relief:

• After the mounts are created, we need to create embosses and holes are to be given.
• To create emboss, create a sketch with the required shape. Project the sketch onto the mounting area but before that extract the surface.
• Now, split the surface to create a hole near the projected area to create an emboss.
• Use the sweep command near the cut section. Now, offset the extracted surface.
• Trim the surfaces together and create a relief hole which is given to such that the screw is fitted into that hole.
• For the Drip Mount part, follow the details given and design the product.
• To create beaks, create the surface in a way that is angular and then trim the surfaces together.

4. Giving the Fillets:

• Once the surface is trimmed, give the fillets near embosses and beads.
• Use the Extrude command followed by the edge fillet to create the sharp edges to the curved parts near the mountings.

5. Creating the Solid:

• After the Surface is created, go to the part workbench and define the part body.
• Use the thick surface option to create the solid with a thickness of 0.75mm.
