Fender Design - Wheel Arch Challenge

FENDER WHEEL ARC:

A FENDER IS THE PART OF A CAR THAT PROTECTS AND FRAMES ITS WHEELS AND KEEPS MUD FROM SPLASHING IT.MOST MODERN 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 IA A "FENDER BLENDER",AND IT IS POSSIBLE THAT YOURFENDER DID GET SLIGHTLY DENTED.SOME OF THE REASONS WHY FENDER BENDER OCCURS INCLUDE.A COLLOSION AFTER A MOTORIST STOPS SUDDENLY AND IS REAR ENDED.A DRIVER BACK OUT OF A PARKING SPACE AND COLLIDES WITH THE CAR BEHIND THIER VEHICLE.WHEEL ARC IS THE SEMI-CIRCULAR PART OF THE FENDERPOSITIONING ABOVE THE WHEEL OF THE VEHICLE.THE WHEEL ARC AREA OF THE FENDER IS USUALLY DESIGNED AS A COVER OR SHEILDOVER THE TYRE ALONG ITS PERIMETER TO STOP ANY DERBIS OR STONES,DIRT,SAND,SNOW ETC.

THERE ARE TWO TYPES OF FENDER:

1)FULL BUMPER TYPE

2)HALF BUMPER TYPE

COMPARING OF TWO FENDERS WE HAVE WIDELY NOW USING A HALF FENDER TYPE INSTEAD IOF USING FULL BUMPER TYPE . BECASUSE THE BUMPER TYPE WANTS MORE COMPONENT THAN THE HALF BUMBER TYPE.IT MAY COST MORE THAN THE HALF BUMPER TYPE.IT WILL MORE TIME PRODUCTION THAN HALF BUMPER TYPE PRODUCE IF ANY DAMAGE OCOURS IN THE FENDER WHILE PRODUCTION. WE WANT TO RE PRODUCTION IT ANOTHER IT MAY COST LOT COMPARE TO HALF BUMPER TYPE.SO WE PREFER NOW HALF BUMPER TYPE.

FENDER REGULATION:

EUROPEAN STANDARD REGULATION

PROCEDURE:

• ACCORDING TO EUROPEAN STANDARDS,THE DESIGN FENDER AND WHEEL ARC SHOULD PASS THE WHEEL GAURD REQUIREMENTS
• TO START THE TEST FIRST WE WANT TO CREATE DATUM THE PLANE USING THROUGH THE OBJECT OPTION TO CREATE PROPER AND PROVIDE CORRECTS
• AFTER THAT WE WANT TO DRAW A SKETCH .TAKE THE MIDDLE POINT OF THE WHEEL AND MARK THE HORIZONTAL LINE AND VERTICAL LINE
• THE HORIZONTAL MUST HAVE THE DEGREE OF 0 DEG TO 180 DEG AND THE VERTICAL REFERENCE LINE SHOLD HAVE 90 DEG RIGHT ANGLE THAT RIGHT ANGLE NAME AS SA
• AFTER THAT TAKE A POINT FROM HORIZONTAL REFERENCE LINE 0 DEG MAKE A MEASUREMENT OF 150 mm AND NAME IT AS SE
• AFTER THAT TAKE 30 DEG OF LEFT SIDE FROM THE RIGHT ANGLE AND NAME IT AS SB.AND TAKE 50 DEG FROM RIGHT SIDE OF THE RIGHT ANGLE AND NAME IT AS SC
• AFTER THAT TAKE A CENTRE BETWEEN THESC AND SE AND MARK IT AS SD

THE CLEARENCE BETWEEN SA LINE AND WHEEL ARC IS +10 mm ALSO THE LINE SA LIES INSIDE THE FENDER SO IT IS POSITIVE VALUE

MEASURING THE VALUES OF CLEARENCE "L" AT ALL SECTION:

MEASURING 'L' AT SB:

MEASURING 'L' AT SA:

MEASURING 'L' AT SC:

MEASURING 'L' AT SD:

MEASURING 'L' AT SE:

TABULATION:

SECTION	CALCULATED CLEARENCE(in mm)	MINIMUM CLEARENCE TO PASS(in mm)	PASS/FAIL
SA	+10mm	+10mm	PASS
SB	+9.9489mm	+10mm	PASS
SC	-0.1137mm	+10mm	FAIL
SD	-3.3964mm	+10mm	FAIL
SE	-7.1327mm	+10mm	FAIL

CONCLUSION:

• THE NEGATIVE SIGN INDICATES THAT THE WHEEL ARC IS BEHIND THE WHEEL
• ALL SESCTION DON'T HAVE THE CLEARANCE VALUE OD +10mm,ONLY SA AND SB IHAVE THE VALUE NEAR TO +10mm
• WHEEL ARC AREA = 20356.728mm^2
