Fender Design

FENDER DESIGN

AIM : From the given CLASS A SURFACE of the FENDER we have to made changes in the design and develop the model with some extra features that are :

Mounting Area

1. Bumper
2. Drip
3. A Pillar
4. Sill
5. Baffel

Introduction:

Fender:

Fender is a part of the vehicle that frames the wheel . The primary purpose of the fender is to prevent sand , mud , rock etc from being thrown away into the air by rotating tire and harm pedestrians.

There is two types of fender in a car body, front fender and rear fender as shown.

Fender can be of two types , full bumper type and half bumper type . Nowadays half bumper type fender is typically used . the cost of sheet metal blank is reduced as we can produce two half bumper type fender in single blank . This also leads to reduction of scrap.

Mounting Area

1. Bumper
2. Drip
3. A Pillar
4. Sill
5. Baffel

Bumper

The bumper mounting area is used to fix the plastic bumper to the fender with the help of the fasteners.

Drip

• It is the important mounting uni of the fender . it is connected with the engine compartment, therefore a lot of design constraints are to be followed while designing the fender
• While designing the drip area we have to initially leave 200-300 mm for the cowl top
• For placing the headlamp we have to leave at least 150 mm at the front while designing the fender
• The cowl top part consists of a wiper motor and its instruments

Sill

The sill is the panel directly below the bottom of the door supporting the floor and may be used to combine the floor and the body. The bottom end of the fender is mounted on the sill body for reinforcement of the fender panel , thus the sill mounting position is designed with holes and emboss. M5 fasteners are used to fix the fenders on the sill body.

BAFFLE MOUNTINGS

Baffle mounting or mudguard are clip-fit types of mounting on the inner side of the fender arch over the Tyre. it protects the car engine compartment and pedestrians from causing injuries from chip-out debris on the road when the car is in motion. they are mounted on the fender using a special type of locking clips which are made up of plastics.

A-PILLER AREA

The A-pillar is the structural pillar that combines the body with the roof . this makes the sides of the windshield rest . front fenders are fastened to the A-pillar to form a robust structure.

TYPES OF BUMPER

Full bumper

Half bumper

GIVEN MASTER SECTION :-

INPUT SKIN (CLASS A SURFACE) :-

DRIP AREA :-

A- PILLAR :-

BUMPER AREA :-

SILL AREA MOUNTING :-

BAFFLE AREA MOUNTING :-

FINAL OUTPUT :-

THE SURFACE IS THEN THICKEN TO 0.75MM TO GET THE DESIRED OUTPUT.

CONCLUSION :

Finally design of fender is done with the help of NX-CAD software by following the master section.
