Fender Design Challenge

FRONT FENDER DESIGN:-

Objective:-

the aim of this project is to design the front fender of a car by tacking into account all design considerations required to design the front fender.

INTRODUCTION:-

Fender:-

fender is the part of vehical that frames the wheel .the primary purpose of the fender is to prevent sand , mud , rock etc from being thrown awway in the engine compartment and air by rotating tyre .

fender can be tow type full bumper type and half bumper type. nowdayes half bumper type fender is typically used.the cost of sheet metal blank is reduced as we can produced tow half bumper type fender in a single blank.this also leads to reduction of scrap.

DESIGN PARAMETERS-

the front fender is manufactured as a seperate part, this is then mounted to the body of car , for this the front fender basically has 5 mounting points.

1-drip area mounting

2-Bumper moumting

3-sill area munting

4-A -piller mounting

5- Splash and Baffel mounting

fender mounting :-

1- Drip area mounting

this is the main portion of the fender which provides the stability to it . while designing the fender ,position of this area is to be calculated from master section. 200 mm space for cowe mounting and wiper motor mounting is needed , as per this consideration poertion should be lest while designing fender further more 10 mm for headlamps unit is to be tacken in to account. maximum depth off drip area not exceed 40 mm,if done so then the spring back effect my get introduced in drip area mounting . proper holes to be created in drip area for fixing it firmly with the frame of vehicle.

2- Bumper area

In this mounting ,the fender connect with the bumper.

the bumper mounting region must be regid in oreder to withstand the force acting upon it duing collision.so, the mounting space can be larger.

1-use the law extension to create surface for baffle mount

2-A 20 mm flage is created for mountings.

2-M6 hole is drill for fastner.

3-Sill area mounting-

The seal mounting area is at the botoom of the fender.

it is mostely gets connected with the door region of the car.

here proper embossing and holes for the fastner was created.

the rib are provided to improve the strenght .

1-extend the sheet to 15mm to make the sheet lenght up to 30mm. giving relief by manualy by creating sketch and trim the sheet both sides.

2-Emboss diamensions are depth 3.5mm and degree 10mm angle is provided. Edge blend is 3mm . trim sheet is used to create 6mm hole.

4- A-piller mounting-

A piller mounting is a vertical support on vehical. it holds the windshield set up

1- Extrude the surface

2-emboss was created and edges are blended

3-m6 holes is drill for fastener.

5-Baffle mounting

this mounting is to fit a wheel arch area gor baffle.

baffle is plastic unit used to fit for splash mounting

creating a holes for fastners.
