FENDER DESIGN

AIM: To design a Front Fender

OBJECTIVE: To design a Fender mounting on the given model by using Master sketch by considering the safety and manufacturing feasibility for possible mounting region.

ABOUT FENDER

The fender is a sheet metal part of an automobile. It Plays a vital role in the automobile industry. This type of coverage covers the engine department from the side and works as a shelter for the wheels. Its primary function is to prevent the passenger who is inside the car while rotating the wheel wheels threw the mud, sand, and some tiny particles this time this fender is working as a shelter that protects and restricts the dirt, sands, and some other particles to go inside the car and in the engine department.

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.

Need of Fender:

• It is designed to provide resistance against wind, muds, and roadside particals.
• It is the sheet of metal covering of the car.
• Fender has a plastic part called Baffle or fender Liner which fits underside the fender to protect the metal from corrosion by stopping the flow of mud and water inside from different road conditions.

There are 2 types of fenders.

1. Full Bumper Type
2. Half Bumper Type

Full Bumper Type: Full Bumper Type is not used now a days because it requires large size of balnk to produce the part and it occupies more space.

Half Bumper Type: Half Bumper Type Half bumper is used because the waste of material is less & can produce two fender at the same time by slightly increase the raw sheet. and to reduce the weight & cost mostly bumper fender are been produced.

Follow the given Master section to create the Drip Area.

MOUNTING AREA

Bumper

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

Drip

• It is the important mounting uni of the fender . it is connected with the engine compartment, therefore a 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 the cowl top
• For placing the headlamp we have to leave at least 150 mm at the front while designing the fender
• The cowl top part consists of a wiper motor and its instruments

Sill

The 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.

BAFFLE MOUNTINGS

Baffle mounting or mudguard are clip-fit types 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.

A-PILLER AREA

The A-pillar is the structural pillar that combines the body with the roof . this makes the sides of the windshield rest . front fenders are fastened to the A-pillar to form a robust structure

Bumper Mounting Area

• It is placed at the front side of the fender,the bumper mount area of fender, mounts on the chassis to hold the position.
• Since Bumpers are mounted over the fender it is called Bumper Mounting Area.

Drip Mounting Area

• The drip area would be recognizable fom the opening between Hood and Fender.
• This mounting is attached to the engine compartment of the car.
• A min 150mm distance is kept from the front side and a distance 300mm or less can be kept on the rear side .
• This is to avoid the springback during the manufacturing . the edge of the mounting should atleast 10mm away from any nearby component in the engine.
• The drip area should be less than 40mm.
• The embosess that are created on the drip mounting should be flat with respect to the curvature.
• A dart is provided at the edge of the drip mounting to increase the stiffness.

Sill Mounting Area

• This is palced basically at the botom of the fender. The mounting part is created such that it firmly fits to the sill.
• The embosess that are created on the drip mounting should be flat with respect to the curvature.

Baffle or Linear Mounting Area

• Usually a baffle is mounted on the fender of the car . It is mounted on the wheel arch area .
• A plastic unit is placed which is called baffle/splash fender linear mounting is placed.
• These mountings are created for fixing the baffle/splash mounting

A-Pillar Mounting Area

• A-pillar mounting is a vertical support on a vehicle. It holds the windshield set up and just downside to the A-pillar fender is mounted to hold the position.

Conclusion: We designed the Front Fender in NX application with proper mountings by using the Master Sketch and Design Parameters.
