Fender Design

FENDER

Aim:

Design a fender by using input class A surface, design Drip area by using a given master section as a reference, and add various mountings like Sill mount, Bumper mount, and A pillar mount.

What is Fender:

A fender is the part of a car that protects and frames its wheels and keeps mud from splashing it. Most modern vehicles have fenders on their front wheels. When you get into a minor car accident, you can call it a "fender bender," and it's possible that your fenders did get slightly dented

Sometimes we can make provision for indicators and rear-view mirror on the fender

Types of Fenders:

1.Full Fender

2.Half Fender

Important areas considering while fender Design:

1. Drip Area
2. Bumper mounting area of a fender
3. Sill mounting area
4. A pillar mounting area
5. Baffle mounting area

• Drip Area
• Drip Area is the area through which the fender is mounted inside the engine Compartment.
• It having some standards specifications we need to consider while designing this area such as from A pillar mounting there should be minimum 200 mm clearance should be there for Cowl top (wiper motor) mounting area.
• The height of the drip mount should not be greater than 40mm to avoid spring back effect and NVH concerns.
• These parameters are following by all OEM brands so ,we should consider while designing this area.

• Use Law extension to extend the sheets for required length, direction and angle.
• Sketches are created and emboss is done by use datum planes.
• Finally, holes are created by using trim sheets.
• The Hole should be 5mm flat surface around the hole.
• Blends are provided as per the master section given.

• Bumper mounting area:

• This mounting connects with bumper portion.
• Law extension commands are used and sketches and plane are created for embossing purpose.
• For getting a flat surface we used emboss as a datum plane, then we offset that for our required depth and trimmed the hole.
• Bridge curves are used for getting smooth surface corners.
• Dart operation is used for creating stiffener like surface for providing enough strength to the flange.

• Sill mounting area:
• This portion is connected at bottom of the car and near to the door.
• Extend sheet command is used for sheet extension.
• Datum plane and sketches are created and emboss is done by using the same datum plane for getting flat surface.
• Bridge curve and Trim Sheet operation are used for getting smooth edges.

• A pillar mounting:
• This area is fixed near to the A pillar Portion and near to cowl top mounting area where this mounting is fastened with A pillar.
• Same curve of surface profile sheet is trimmed and law extension.
• Datum plane and sketches are created and emboss is done by using the same datum plane for getting flat surface.
• Bridge curve and Trim Sheet operation are used for getting smooth edges.

• Baffle mounting area:
• This Area is place at wheel arch portion, it is bottom portion over the type face.
• In this area baffle is mounted with the clips, baffles used to prevent road debris going in to the engine bay and doors.
• By using bridge curve option, we trimmed required as per required portion and sketches are done.
• Then holes and curves are trimmed for holding clips arrangements and clearance to avoid stress concentration.

Conclusion:

We Created fender mountings ares, and created drip area by using master section provided.
