Fender Design - Wheel Arch Challenge

Aim:

To decide wether the design is whether the european standards or not.

Fender :

Fender is a part of an automobile, motorcycle 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.

The main purpose of fenders on cars is that they shield the wheels and they protect the passenger the pedestrains and the other vehicles from stones, mud, liquid and other debris that can fly in the air because of the speeding rotating wheels while the car is running.

Wheel Arch :

It is a curved part of the fender positioned right above the wheel. The wheel Arch is designed such that it protects both the pedestrian and car cabin from mud, water rocks and other road spray. Different countries have different wheel arch regulations in place, and the wheel arch design has to comply with them to be deemed usable in that country.

Given design:

WHEEL ARCH:The wheel arch is the semicircular part positioned above the wheel of a vehicle. The most important body change was that the front wheel arch was cut higher into the fender. Corrosion had occurred around the splash plate at the back of the wheel arch.

FENDER :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. It is the part of a car, truck or motorcycle that surrounds the wheel sell. The primary function of a fender is to prevent dirt and debris from being thrown into the air by the tire. The fender is located over the wheels of the vehicle. As such,there are four fenders on a typical vehicle: front right,front lef t, rear right and rear left.

1. FULL FENDER TYPE: Full fender type is traditional type of fender where more materialconsumption is observed. This type is used in old design of automobiles where it increases the overall weight and thus reduces performance. The maintenance also relatively more due to more surf
2. HALF FENDER TYPE: Half fender type is modern design where less material consumption is observed,so productivity increases by reducing size of blank and thus providing more The maintenance also relatively low compared to full bumper type.

JAPAN REQUIREMENTS FOR FENDER WHEEL ARC:

1. Measure clearance L of tire,hub,cap,and fender in three different positions within area K and produce clearance check chart to validate.
2. Clearance must be greater than 5mm in all the three positions.
3. Wheel guard requirement: the value a shall be more than 5mm at a line 30*forward and 50*rearward from the centralvertical axis of axis of wheel

US STANDARDS REGULATION FOR FENDER WHEEL ARC:

1. Make clearance check details on all positions from -100* to 100* and make the clearance check table.
2. All values should be greater than 5mm to satisfy the regulatio
3. The value of 'a' shall be more than 5mm at a line 30* forward and 50*rearward from the centralvertical axis of axis of whee

EUROPEAN REGULATION:

Measure CL L at section SA-SA-SB-SB-SC-SC-SD-SD-SE-SE and produce CL check chart to validate.

1. At all five sections the CL L value should be greater than 10mm to satisfy the European regul
2. Wheel guard requirement: the value of a·shall be more than 5mm at a line 30 degree forward and 50 degree rearward from the central verticalaxis of axis of wheel.

PROCEDURE:

1. According to the European standards,the design fender and wheelarc should pass the wheel guard requirement proced
2. To start the test, first create a plane with origin as center of the wheel plane.
3. Then sketch using lines along with given dimensions as SA,SB,SC,SD and SE.
4. After sketching proj ect the intersection points on to the fender
5. Then use measure distance tool and calculate the clearance between sketch lines and wheelarc.

CONCLUSION: From the above results we can conclude that the fender does not pass the European regulations,as the minimum clearance L between the fender wheel arch and wheel for vehicle and pedestrian safety is lOmm and this design does not meet the requirement.
