Fender Design
FENDER:-
Fender is the part of an automobile, motor cycle 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.
Sticky materials, such as mud, may adhere to the smooth outer tire surface, while smooth loose objects, such as stones, can become temporarily embedded in the tread grooves as the tire rolls over the ground. These materials can be ejected from the surface of the tire at high velocity as the tire imparts kinetic energy to the attached objects. For a vehicle moving forward, the top of the tire is rotating upward and forward, and can throw objects into the air at other vehicles or pedestrians in front of the vehicle.
TYPES OF FENDER
- Full Bumper type
- Half Bumper type
MOUNTING
- Bumper
- Drip
- A Pillar
- Sill
- Cowl/Bumper
Data given for Designing Fender
TASK 1 : Create the Drip Area
CREATE THE DRIP AREA USING THE MASTER SECTION.
ADD THE RIBS TO PROVIDE STRENGTH.HERE 1MM THICKNESS IS GIVEN AS BODY THICKNESS IS 0.75MM.
TASK 2 : Create A pillar Mount
INDIVIDUAL EMBOSES PROVIDING MORE STRENGTH TO THE A PILLAR MOUNT,ALSO THE EDGE FILLETS ARE PROVIDED 5MM.
Task 3 : Create Bumper Mount
EMBOSSES ARE 3MM DEEP,WITH 5MM DIA HOLES.
TASK 4 : Sill Mount
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.
Task 5 : Cowl/Bumper Mount
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 OF THICKNESS TO THE SURFACE .
The thickness of 0.75 mm inward on the final sewed surface of the fender to the sheet metal parameters.
DIFFERENT VIEWS OF FENDER :
CONCLUSION :
Finally design of fender is done with the help of NX-CAD software by following the master section
