Fender Design

                                                          FENDER DESIGN

AIM : The objective of the project is to design a front fender from a skin data and provide the all necessory mounting bracket according to the master section given.

INTRODUCTION 

Design of any product starts from an requirement.The design engineer sketches the product based on the requirement.Then the 2D sketch with the proper dimensions is converted into the 3D model using the advanced CAD software's.The another important thing in the design is that, every product that is designed should be able to manufactured.So the role of the design engineer is to design the product that can be easily manufactured and with less cost effective.This is the place where the Design for manufacturing [DFM] and Design of assembly [DFA] takes a role while developing any product.The process of development design carries on until the design satisfies the customer needs.Here in this project the product that we are going to develop is a car fender.

FENDER

The main purpose of the fender is preventing sand,mud, rocks,liquids and another road spray from being thrown into the air by the rotating tire.There are 2 types of fender,

1. full bumper type

2. half bumper type

 

Presently we are using the half bumper type,because of the reason for choosing half bumper type is that when we choose the full bumper type the blank used for creating it is very large and it 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 actually.In half bumper type we reduce the usage of the steel material and uses the lots of plastic on the bumper which in term decreases the cars weight and increases the overall performance and mileage.

MOUNTING REGIONS OF FENDER

There are 5 mounting regions for fender,

1. Drip mounting 

2. Body mounting

3. A pillar mounting

4. Sill mounting

5. Bumper mounting

METHODOLOGY

GIVEN DATA:

MASTER SECTION

DRIP AREA DESIGN

                                                                                           It is the important mounting unit of the fender.It is connected with engine compartment,therefore there are 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 from the cowl top.For placing the headlamp we have to leave at least 150 mm at the front while designing the fender.

SILL MOUNTING

Sill is the part 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.

BUMPER MOUNTING 

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

A-PILLAR MOUNTING

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.

DESIGN OF BAFFLE MOUNT 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.

APPLYING THICKNESS TO THE FENDER

The fender has given a thickness of 0.75 mm.

VIEWS OF FENDER

CONCLUSION

THE FENDER IS SUCCESFULLY DESGNED ACCORDING TO THE MASTER SECTION AS WELL AS ALL THE OTHER DESIGN RULES.
