Fender Design

AIM :

To design the car fender according to the given design parameters related to industry standards using Catia V5.

FENDER :

The part of the car covering the wheel has two very different names depending on whether you’re coming from a British viewpoint or an American one.

Although nowadays the fender/wing covering the wheel is very much part of the overall car body, in the early days of car design the wheels were more remote from the chassis, and so to stop all manner of grubby bits flicking up at high-speed from the wheels into other road users (and all over your own gleaming coachwork) there needed to be some kind of extra guard.

To the British designers of the day these extra panels sticking out from the main body – with sweeping, flowing curves – resembled the wings of birds, and so the name was given. Over the years the name has stuck to some extent, but with the wheels of modern cars becoming ever more integrated into the overall form of the car the idea of a ‘wing’ seems a bit vague, and so these are often now simply called ‘arches’ or ‘panels’ (or ‘bumpers’ if they’re at the points likely to make contact with other vehicles, like the front and back). Indeed the term ‘wing’ to a British youngster would usually conjure up images of a spoiler attached to the back of a car.

In the US these wheel-covers were given a name that reflected their purpose rather than the way they looked, and so the piece of metal which guards the detritus flying up from the road was called the ‘fender’ – literally fending off the attack of the muddy roads. As time went on this function still applied, and therefore so did the name. In the states, a small incident that might be called a ‘bump’ by a Brit where the bumper makes contact with something, would often be called a ‘fender bender’.

USES OF FENDER :

• Get other vehicles or pedestrians on the roadside dirty
• Hurt pedestrians
• Scratch the bodies of other vehicles
• Cause minor, and even major damage to other vehicles

TYPES OF FENDER:

There are mainly two types of fenders :

1. Half bumper type

This half bumper type is used for mainly cost and material cutting purposes as this type is also provided ease of manufacturing and the strength is also improved for the half bumper type fender.

2. Full bumper type

The full bumper type model is used in the olden days this creates much wastage of material and the unnecessary cost is increased.

INPUT DESIGN PARAMETERS:

Design of Drip Area:

• It is the important mounting unit 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
• Cowl top part consists of a wiper motor and its instruments

Design of Bumper Mounting Area:

• It helps to fix the plastic bumper to the fender with the help of fasteners.

Design of Baffle Mounting Area:

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 Thickness to the Part:

The fender is thickened by 0.75mm.

Conclusion:

Finally, the design of the Fender is done with the help of the Input and Master Section using Catia V5.
