Fender Design

Question:

Follow the given Master section to create the Drip Area

For the Sill, Bumper, Baffle(Splash), and A-Pillar mount create your own design according to the Engineering standard that you learned.

Prepare a report with all the relevant images included for the mounting points created.

Solution:

Introduction to Fender:

• Fender is the part of the bedy of vehicle which covers the wheel and the engine compartment.
• The fender is provided in such a way that it will protect the padestrians from the high impact from the engine comapartment.
• The fender is also the cover made in such a way that the customer won't see the internal ugly areas of the engine compartment.
• It is made up of pastic or softer material so that the impact of the fender on the pedestrians is less.
• The Fender part is of two types:
  • Full Bumper Type
  • Half Bumper Type
    
• Generally full bumper type fenders were used but to reduce the waste material half type fenders are used in most of the cars.
• There are 5 areas of mouting:
  
  1. A-Pillar Mounting
  2. Body Mounting
  3. Sill Mounting
  4. Bumper Mounting
  5. Drip Mounting

Design Methodology:

Master Section to create the Drip Area Mounting

1. • It is the important mounting uni of the fender. It is connected with the engine compartment, therefore the 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 cowl top
   • For placing the headlamp we have to leave at least 150 mm at the front while designing the fender.
   • Cowl top part consists PF wiper motor and its instruments.
   • Two darts are added on the longer side of the drip area in order to provide the stiffness and adds strength to the part . This helps the fender to not to vibrate and impact the forces outside of the fender during motion of the vehicle.
   • Embossing are provided on the mounting to strengthen them during fastening.
2. Mounting on the Sill 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 . M5 fasteners are used to fix the fenders on the sill body.

     DESIGN OF BAFFLE MOUNTING AREA :

     • Baffle mounting or mudguard are clip fit type 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.

       CONCLUSION :

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