Fender Design
DESIGN OF CAR FENDER
FENDER:
It 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.

Now 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 this 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 REGION:
OBJECTIVE:
The main objective of this project is to design a fender using a new age design software - NX – CAD.
GIVEN MASTER SECTION:
DRIP AREA:
It is the important mounting unit of the fender. it is connected with the engine compartment, therefore the lot of design constraints are to be followed while designing the fender embossing are provided on the mounting to strengthen them during fastening.

BEAD COMMAND:
Here I used bead command instead of the dart. Three beads are added on the longer side of the drip area in order to provide the stiffness and adds strength to the part. This helps the fender to not to vibrate and impact the forces outside of the fender during motion of the vehicle.

SILL MOUNTING:
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.

BUMPER MOUNTING:
Bumper mounting area is used to fix the plastic bumper to the fender with the help of the fastener.

A-PILLAR MOUNTING:
The A -pillar is the structural pillar that combines the body to the roof. This make the sides of the windshield rest. front fenders are fastened to the A -pillar to form a robust structure.

BAFFLE MOUNTING:
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.

THICKEN:
The thickness of 0.75 mm inward on the final sewed surface of the fender to the sheet metal parameters.
