Fender Design

* Problem Statement -
- 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.

- Follow the given Master section to create the Drip Area And For other Sections We Can assume The Diamensions.

 

Solution:

Introduction to Fender:

- Fender is the part of the body 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:
1. Full Bumper Type
2. 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

1. Mounting on The Drip Area.

- 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.

3.Mounting on the Bumper Area.

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

4. DESIGN OF 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. Front fenders are fastened to the A-Pillar to form a robust structure.

5. 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.

* Now By Using Thickning Command We Give Thickness To The model Ans As We all knoe that the minimum thickness of the sheet metal body is 0.075 mmThickness, so We Give Same thickness.

CONCLUSION :

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