Fender Design

Fender Design

OBJECTIVE :

The main objective of this project is to design a fender using CATIA V5

INTRODUCTION :

Design of any product starts from an requirement . The design engineer sketches the product based on the 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 of 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 to prevent sand,mud, rocks,liquids and another road spray from being thrown into the air by the rotating tire .

TYPES OF FENDERS :

There are two types of fenders , they are

1) full bumper type

2) half bumber type

• 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 material and 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
• Baffle mounting
• Sill mounting
• Bumper mounting
• Drip mounting
•

CONCLUSION :

Finally design of fender is done with the help of CATIA V5 software by following the master section.
