Fender Design Challenge
Aim:
To design Fender and main parts of these project ventures . it's main parts are Sill mount,Bumper Mount and A- Pillar mount as per given moduel.
FENDER:
A fender is a requirement for all cars and trucks. These fenders are there for important reasons and not just for coverings. What is a fender of a car – fender car part explained?
A fender is the part of a car, truck, motorcycle, or other vehicles that frames or covers a wheel well. Its main purpose is to prevent debris, rocks, mud, liquids, sand, and other road debris from getting thrown in the air while the tires rotate.
The “fender” typically refers to the front panel that covers the front wheels, and the “quarter panel” typically refers to the rear panel that covers the wheel that also includes the roof pillar. The “bumper” is the front and rear ends of a motor vehicle to absorb impact in a minor collision.Fenders also enhance the car’s aerodynamics. They also prevent mud, sand, rocks, liquid, and all sorts of debris from being thrown in the air while you’re driving your car.
FENDER TYPES:
The fender is having two diffrent types based on it's coverd postion in car .
Full bumper finder and Half bumper fender:
The full bumper finder is used for old type cars among 1937- 1980 s in american version it's look like bounded like big circle arc.; due to it's large size material and weight is more brtile .so, the perfomance of car pulling and force will be reduce speed and millage range .In indian range known Ambaster car .Here the material wastage and design cost is more estimation . Where contraction time and delivery time also more
The design and material like high weight to reduce milage and place to maintain low safety compare to indian range towns.
The maintance and rust material like CI material and low design models.
HALF Size bumper Fender:
Half size compare to old type hence it's known as half size fender . here the low crap and low cost material are used hence it's have low maintance in rust and place occupation so better safety . The conctracion have low time and high design improvements in OGEES and constomers option to improvement like spical perpose also .
The low weight manage millage and cost .
Explation: The fender contraction design make these four different portion are consider to design mount .The Area to be consider whie Design Fender ;They are
- Drip area
- Bumper Mount
- Sill Mount and
- Body Mount
.The skecth give
Drip Area:
The Drip Area is connection of the Fender with Engine compartment. It's attached to Engine housing through fasteners.
There should be same consideration followed to design the drip area, from back side of the fender there should be 200mm clearance for cowl mounting area from the front there should be 150mm clearance for the Head lamp housing unit.
Considering the above desing constrians in drip area .Embosses are provided to increase strenght ,corners of the flange are smoothen to ease of the prodution . Unifrom wall thickness 0.75mm.
* Design Consideration for drip area 150mm distance from front end of the Fender.
* another gap is filled with head lamp 200mm at rear end of the fender with wiper motor assembely .
* Intially 3-degree angle and 9mm length is given while creating a drip area because the engine component should not make Spring back and out side visiable .
* The depth of drift should be between 40-60mm .if depth exceed 60mm it's form Spring back wrinkles and vibration from external .Embosses and ribs are given strenght.Embosses dimensions are depth 3.5mm & 15 degree for three embosses.
A PILLAR AREA :
A pillar area is a front windshied of the car. It's mounted on the pillar by means of fasteners.Here the proper embossing are provinded along with holes for fastener.
* Law of extension dimensions are 42mm lenght and 90degree of angle. Offseting the law extension face 5mm .Creating hole 5mm.Edge blend and face blend 2mm.
The SILL MOUNTING:
The sill Moutindg area is in the bottom of the Fender .
* It 's mostly gets connected with the door region of the car .
Here , proper embossing and holes for the fasteners are provided.
The ribs are provided to improve the strength.
* Extened sheet to 15mm to make the sheet lenght 30mm . Giving relief by manual like creating a stekch and trim sheet both sides. Emboss dimensions are depth 305mm and 15 degree of angle .
Edge blend is 3mm . Trim sheet is used to create a 6mm hole on sheet.
BUMPER MOUNTING AREA :
In These Mounting , the Fender connects with the bumper.
The Bumper mounting region must be rigid in order to withstand the face upon it during collision .So,
the Mounting space can be larger.
* law of extension lenght 20mm & 75 degree of angle .Skecth to joint the surface . Draft angle 45 degrees, depth 4mm and radius 3.75 mm .
*Create two drafts in existing spaces as shown .Trim sheet is used to create a hole of dia 5mm .
* For skew use 3mm edge blend and for dart and embosses 2mm edge blend .
BAFFLE AREA :
The Baffle Area is made for down shod to mounting the Fender to support and grip during movements .
* it's placed and three or more holes make for the fasteners by holes in 5mm.
* Creating holes for baffle ,Trim sheet feature is used to creat holes of 5mm.
* There are three or more baffle is used to fix it stable and mount with base of car wheel arch.
Conclusion :
Developed the Fender as per given skiecth religions and formates Arears.They are like Drip, Sill, A pillar and Baffle mounting areas by design requieds of the Fender design.
