Fender Design

Fender Design

Objective: To design fender from given skin data and master section.

Functions:

• To stop any foreign materials or debris entering in engine compartment such as mud, gravels, water. This may compromise functioning of engine and other vital components.
• It acts as a guard to provide protection to the pedestrian or any other from moving wheel at a time of collision.

Types of Fender:

There are mainly two types of fender.

• Full Fender
• Half Fender

Full Fender:

• Full fender is a whole integral part with bumper and side door as shown in image.
• Full fender was used in previous generational cars where majority of components were made by sheet metal.
• Main drawback of full fender is it uses more sheet metal along with higher scrap produced during manufacturing.
• Limited aesthetic looks can be given due to sheet metal, increased vehicle weight and difficult to manufacture.

Half Fender:

• As a name suggests it is only made in half part where other parts are joined by means of fasteners with various body parts.
• It is joined to bumper and side door separately.
• It uses less sheet metal, reduces scrap and easy to manufacture.

Mounting Points for Fender:

There are major five points used for mounting of fender.

• Drip Area
• A-Pillar
• Bumper
• Sill Area
• Baffle Area

Master section for drip area mounting was given. According to that drip mounting was designed.

Master section is given below.

The features used for the design of fender are given below:

oSketch: To sketch desired shape and dimensions were given.

oProjection of curve: Sketching were projected on various surfaces using this command.

oCurve on surface: To draw sketch on required surface.

oDatum Plane: Planes can be created to draw sketches on different shaped surfaces.

oLaw extension: To extend surface from existing surface.

oTrim surface: To trim unnecessary surface.

oSew: To joint different surfaces.

oDart: To create rib where two different surfaces joined at specific angle to provide additional strength

oEdge/Face Blend: To give radius at two mating surface or edges.

oEmboss: To create emboss on surface for strength.

Fender metal thickness is kept 0.75mm.

Different mounting points are shown below:
