Fender Design

fender design

INTRODUCTION:

Fender is the American English term for the part of an automobile, motorcycle or other vehicle body that frames a wheel well (the fender underside). Its primary purpose is to prevent sand, mud, rocks, liquids, and other road spray from being thrown into the air by the rotating tire. Fenders are typically rigid and can be damaged by contact with the road surface.

OBJECTIVE:

In this project we are going to design the mounts for the Front fender such as drip, sill, bumper, A-pillar, cowl and baffle for this we are going to design mounts.

DESCRIPTION:

In this project as we said we are going to design the front fender mounts.

TYPES OF FENDERS :

There are two types of fenders , they are

1) full bumper type

2) half bumber type

FENDER WHEEL ARCH :

• Fender wheel arch is having some standard specifications , for example if you see the car from the front, if you see the wheel outside fender it does more chipping and it causes lots of damage to the pedestrians and also to the car
• In order to maintain the pedestrians safety we have to position the tire wheel inside the fender
• For the European requirement the clearance between the wheel and the fender outer most skin is 5mm
• This requirements changes from country to country based up on the road conditions

MOUNTING REGIONS ON FENDER :

There are 5 mounting regions on the fender , they are

• A- pillar mounting
• Body mounting
• Sill mounting
• Bumper mounting
• Drip mounting

DESIGN METHODOLOGY :

GIVEN DATA :

As per the master sketch we are going to design the drip mount and we will follow the design parameters as per industry for the other mounting area too.

And we are going to design the fender in catiav5

So first we are going to work on the drip mount which will mounted to the engine compartment.

Drip mount

As you can see in the above images we have created some emboss and mounting holes for the fasteners we have created flat surface and have given the minimum 5mm flat area around the mounting holes.

And we have also provided darts to it to increase the strength of the mount.

Sill mount

Like drip mount we have created the sill mount too and we made sure that we didn’t have any sharp corne

Bumper mount

As you can see we have created the bumper mount using emboss, cut out the sharp corners.

A-PILLAR Mount

While creating this mount was tricky one as we have create a emboss on curved surface so for that we have used datum plane and according to that we have created the sketch.

BAFFLE Mount

For baffle mounting we didn’t made any kind of emboss we have created the mounting holes for it and we have created the baffle flange on which the holes are there.

After creating the mounts we finally thicken it which gives thickness to the sheet meta.thickness is 0.75mm

So the above image is the final fender part.

CONCLUSION:

As we successfully learn about the feature and purpose of front fender and made it in catiav5 and we have learn the tools involved in it.
