Fender Design

FENDER DESIGN

AIM:

To designing the fender using of NX cad software.

FENDER:

Fender is a part of an automobile or other vehicle body

that frames a wheel well (the fender underside). Its primary

purpose is to prevent sand, mud, rocks, liquids, and other

road spray from being thrown into the air by the rotating tire.

Fenders are typically rigid and can be damaged by contact with the road surface.

The main purpose of fenders on cars is that they shield the wheels and they protect the passengers, the pedestrians, and the other vehicles from stones, mud, liquid, and other debris that can fly in the air because of the speeding rotating wheels while the car is running

TYPES OF FENDER:

• Presently we are using the half bumper type , the reason for choosing the half bumper type is that when we choose the full bumper type the blank used for creating it is very large and also has the lot of wastage , but in the case of the half bumper type we have the possibility to reduce the scrap . This is what we called as scrap management
• In half bumper type we reduce the usage of the steel materialand uses the lots of plastic on the bumper which in term decreases the cars weight and increases the performance

• MOUNTING REGIONS ON FENDER :

  There are 5 mounting regions on the fender , they are

  • A- pillar mounting
  • Body mounting
  • Sill mounting
  • Bumper mounting
  • Drip mounting
  • 

  • GIVEN DATA :

  • 

    DRIP AREA MOUNTING :

    • It is the important mounting unit of the fender. it connected with the engine compartment ; there for the lot of design constraints are to be followed while designing the fender
    • While designing the drip area to initially leave 200-300 mm for cowl top
    • For placing the head lamp leave at least 150 mm at the front fender
    • Cowl top part consists pf wiper motor and its instruments.
    • Embossing are provided on the mounting to strengthen them during fastening
    • 
    • SILL MOUNTING AREA :
      • 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.
      • 

        BUMPER MOUNTING AREA :

        • Bumper mounting area is used to fix the plastic bumper to the fender with the help of the fasteners
        • 

        • A-PILLAR MOUNTING AREA :

          The A -pillar is the structural pillar that combines the body to the roof . this make the sides of the windshield rest .

        • 

        • BAFFLE MOUNTING AREA :

          Baffle mounting or mudguard fit type of mounting on the inner side of the fender arch over the Tire . it protects the car engine compartment and pedestrians from causing injuries from chip out debris on the road when the car is in motion .

        • CONCLUSION :

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