Fender Design Challenge

                                                   FRONT FENDER DESIGN

Objective: Designing a front fender from the given skin data and the master section provoded with Drip mounting,A-piller, Sill, Bumper, C-mountings and splash mountings.

Front fender:

• Fender is an automobile part. A fender is diffrent than a bumper because it's a metal structure that frames the wheel well of your car, instead of the front or back.
• The fender extends between the front door to the front bumper covering the front wheels of the vehicle.

                    

                                                            FRONT FENDER

• When vehicle is moving, tyres pick up stones, mud, sand and other road spray from being thrown into the air by the rotating tire in all directions and hurt pedestrians.
• Fenderes are bassically present to prevent any injuries to pedestrians.
• Two types of fenders are used:

            1.Full bumper type

                                     

          2.Half bumper type

                                      

 Objectives to design:

• Fender Drip area mounting
• A-piller mounting area
• Sill mounting area
• Bumper mounting area
• Baffle region

                     

  Fender Skin data:

            

Master section to create drip area:

                     

1. Fender drip area:

•  Drip area mounting is a major and critical mounting area located inside the engine compartment.
• The design considerations are same throught all cars follow standard design considerations.
• Drip area designed according to the master section provided.

                

• Drip area will is either spot welded or in some cases bolted with screws to the bracket placed inside the engine compartment.
• The hood side depth of the drip achived 45.80mm
• Thickness of the fender (t) = 0.75mm
• Holes are provided on the weld surface of Drip area  (d)=5mm 

                             

• For increasing regidity and strength of the fender drip area "Dart" are provided to the drip section.

Dart: 'Dart' is a feature generally given in sheetmetal part to protect the part to get springback effect.

                         

2. A-piller mounting area:

• Pillers are vertical supports on a vehicle. they are located around all glass on automobile.
• Pillers provide structural intigrity to the vehicle, primarily the roof. 
• The "A-piller" holds the windsheeld in place.

                    

3. Sill mounting region:

•  Sill mounting region is located at bottom side of fender where the door meets the frame when it closed.

                                           

4. Bumper mounting area:

•  Bumper is a stracture attached to or integrated with front end of the fender of vehicle.

                   

5. Wheel arch mountings:

• Wheel arch is a semicircular positioned above the wheel of a vehicle attached to the fender.
• This structure clamped to the fender using fasteners.

                               

6. Side marker indicator :

• Car front fender side marker indicator light is placed on fender surface.
