Aim - Design of Front Fender using NXCAD

• Fender :

Fender is the US English term for part of an automobile (vehicle body of the car) that frames the wheel nicely (for fender underside). Its primary purpose is to shield wheels and protect passengers’ compartments and pedestrians from the projection of water, mud, and stones.

Fender is one of the styling components which is exposed to the customer front and cannot be welded. Most of the assembling is done using fasteners, retainer clips, and proper fitting.

Fenders are either made of steel or thermoplastics.

• Steel versus Plastic Fenders:

• Types of Fenders :
• Full Bumper Type :

• Half Bumper Type Fender

• Mounting Points of Fender :
• A-Pillar
• Bumper
• Sill
• Drip Area
• Splash Cover / Wheel Well

• Design Data Provided :
• Master Section Given :

• Software Used for Designing: NXCAD 12
• Design of Fender :

The main objective here is to design Drip Area, Bumper Mounting region, Sill mount region, A-Pillar mount region, and splash cover or wheel well mount regions for the given fender skin or styling surface.

• Design Considerations :
• Embosses are provided to increase strength.
• The corners of the flanges are smoothened to ease the productivity of the part.
• Fillets of 2-4 mm are provided to avoid sharp corners and edges.
• Cutouts are provided in certain regions in order to save materials.
• A Uniform wall thickness of 0.75 mm is maintained.

A-Pillar Mount Region:

• Bumper Mount Region :

• Sill Mount Region :

• Drip Area :

Ribs or structural beads are provided to give structural support and strength to the flange.

• Splash Cover or Wheel Well Mount Regions :

• Slot for Mounting Turn Signal :

• Final Fender Design :
