Fender Design - Wheel Arch Challenge

REPORT.

Fender Design - Wheel Arch.

OBJECTIVE:- To understand design consideration of fender as per automobile regulations in various region like

japan, european, u.s. and measure tolerance between wheel and fender.

INTRODUCTION:-

WHEEL ARCH:- Is edge of fender/ bottom most trim near wheel, fenders main purpose is to cover engien compartment from side and as whell arch is part of fender so fender is design in a way that it protects engien from hitting any chiped particle by wheel when in motion, it is also for pedestrian seafty as chiped parts can be blown away by wheel to avoid this, some regulations are set by automobile authority of different region according to road conditions.

JAPAN REQUIREMENTS FOR FENDER WHEEL ARC:

US STANDARDS REGULATION FOR FENDER WHEEL ARC:

EUROPEAN REGULATION:

PROCEDURE: WHEEL ARCH TESTED METHOD USED IS EUROPEAN USING NX.

CREAT A PLANE ON OUTERMOST EDGE OF WHEEL.

Figure1. plane creation.

craetion of 5 points as per regulation for testing.

Figure2.point creation

projection of points on fender.

Figure3.projection of points

measure distance between intersectinc and projected points on fender.

POINT 1.

DISTANCE=10.00MM

POINT 2.

DISTANCE=9.9490

POINT 3.

DISTANCE= -0.1139

POINT 4.

DISTANCE= -2.8875

POINT 5.

DISTANCE= -5.9973

CONCLUSION:

EUROPEAN STANDERD	REQUIRED CLEARENCE	OBTAIN CLEARENCE	RESULT
POINT. 1	10mm	10.00mm	PASS
POINT. 2	10mm	9.9490mm	FAIL
POINT. 3	10MM	-0.1139mm	FAIL
POINT. 4	10mm	-2.8875mm	FAIL
POINT.5	10mm	-5.9973mm	FAIL

AS OBTAIN MEASURMENTS DOES NOT MEET THE CRITERIA OF EUROPEAN STANDERDS SO THE FENDER CAN NOT BE MADE, NEED TO WORK ON DESIGN AND MAKE DESIGN FISIBLE FOR EUROPEAN STANDERDS.
