Design of backdoor

REPORT:

BACK DOOR DESIGN:

BACK DOOR ARE ONE OF THE TYPE DOORS OF THE VEHICLE WHICH ARE LOCATED NEXT TO THE PASSANGERS SEAT WHICH PROVIDES ACCESS TO THE LUGGAGE COMPARTMENT.IN MOST OF THE CARS THESE BACK DOORS ARE OPERATED WITH THE HELP OF GAS STAY WHICH IN TURN REDUCES THE EFFORT REQURIRED TO LIFT OPEN THE DOOR.THE BACK DOOR IS A HINGED DOOR\TAILGATE AT THE REAR OF THE VEHICLE.IT MAY BE USED FOR LOADING AND UNLOADING CARGO,OR TO GET PASSENGERS IN AND OUT,IN CASE THRE ARE SEATS PRESENT AT THE REAR.

THE GAS STAY ARE THE LIFTER THAT ARE USED IN CARS LIKE HOOD OR BACK DOOR THAT ARE USED TO LIFT THE CARS TO OPEN THE DOOR AND IT WILL GIVE SUPPORT TO CAR TO STAY IN POSITION WILE REPARING OR KEEPING LUCKAGES IN CAR CARRAGE.

THERE ARE DIFFERENT TYPES OF BACK DOOR PANNEL:

1)OUTER PANNEL

2)INNER PANNEL

3)OUTER LOWER PANNEL

1)OUTER PANNEL:

• THRE OUTER PANNEL WE WANT MAKE .FIRST WE WANT TO GET THE SYLED SURFACE FROM THE SYLISH TEAM TO DEVELOP THE SURFACE.BEFORE STARTING THE WORK TO DEVELOP THE SURFACE WE FIRST WANT TO REPAIR THE SURFACE THAT HAVE SOME MISTAKE IN IT
• FIRST WE WANT TO INFORMORMED TO STYLED TEAM ABOUT THE PROBLEW THEY WILL GIVE THE REPAIR OR VERY SMALL MISTAKES WE CAN REPAIR IT.AFTER REPAIR THE SURFACE WE WANT TO SEW THE SURFACE TO CHECK IT
• LETS START TO DESIGN THE OUTER PANNEL FIRST WE WANT TO EXTRACTED THE UPPER AND LOWER SURFACE AND HIDE THE BECAUSE WE DONT TOCH THE PARENT SURFACE.AFTER TAKING THE EXTRACTED SURFACE
• WE WANT TO REPAIR THE SURFACE BY HIDE THE MISTAKEN SURFACE AND USE BRIDGE CURVE OPTION AND USE THROUGH CURVE MESS TO MAKE THE PROPER SURFACE AFTER MAKING SEW THW WHOLE THE SURFACE WE MAKE IT
• WE WANT TO OFFSET THE SURFACE OF (0.75*2)+2mm DOWARD RHE SURFACE TO GET THE CORRECT SURFACE OF IT

2)LOWER PANNEL:

• AFTER MAKING THE OFFSET THE SURFACE WE WANT TO USE THE OPTION OFFET CURVE ON SURFACE OPTION IN UPPER SURFACE AND LOWER SURFACE OF THE BACK DOOR AND USE TRIM SHEET OPTION TO TRIM THE SURFACE
• CHECK THE TRIM SURFACE THAT WE WANT THE SURFACE WAS TRIM IT .IF IT WAS WRONG SURFACE WAS SELECTED THEN USE SHIFT+RIGHT BUTTON TO UNSELET THE SURFACE.THEN CLICK THE SURFACE TO SELET IT
• AFTER MAKING TRHE SURFACE WE WANT TO MAKE THE TOOLING AXIS TO GET TOLLING DIRECTION OF THE SURFACE .WE USE ALL THE LAW EXTENSION IN USE OF PULLING DIRECTION WITH TOOLING AXIS
• AFTER USE TRIM SHEET OPTION TO GET THE SURFACE WE WANT TO USE BRIDGE CURVE OPTION TO MAKE THE CURVE ON THE SURFACE.AFTER MAKING THE CURVE WE WANT TO FILL THE SURFACE
• FOR THAT WE WANT TO USE THE THROUGH CURVEW MESS .THIS IS USED TO MAKE THE SMALL AREA AND IT IS BEST OF IT.

i)CONNCTING FLANGE:

• FIRST WE WANT TO MAKE THE OUTER MOST FLANGE TO JOIN THE SURFACE.FOR THAT WE WANT TO TAKE THE OFFSET OF THE SURFACE THE WE WAN TO DEVELOP THE SURFACE
• THEN USE OFFSET CURVE OPTION TO OFFSET THE SURFACE AND USE THE p36 OPTION IT IS EXPRESSION THAT GIVE CORRECT VALVE OF 30mm OF BEFORE WE USED OFFSET CURVE SURFACE IN THE LOWER SURFACE
• AFTER THAT USE TRIM SHET OPTION TO TRIM THE SURFACE THEN MAKE THE BRIDGE CURVE TO JOIN TJHE CURVE TO MAKE THE SINGLE SURFACE USE THROUGH CURVE MESH SURFACE TO FILL THE SURFACE
• WHILE CONNECT THE OUTER FLANGE AND LOWER FLANGE THERE IS SMALL GAP IN FOR THAT WE WANT TO MAKE THE SURFACE TO JOIN THE SURFACE THE TWO SURFACE.

3)OUTER LOWER PANNEL:

• FIRST WE WANT TO MAKE OFFSET OF THE SURFACE TO INSIDE OF 25 mm.to make the outer most flage of the surface
• WE WQANT TO USE THE OFFSET OF CURVE OPTION TO OFFSET THE CURVE TO 40 mm TO THE SURFACE AFTER THAT WE USE p36 IT FOR USE THE CURRECT VALVE TO OFFSET FROM OFFSETED CURVE OF 30mm AND TRIM THE SURFACE WE WANT TO MAKE THE FLAGE
• AFTER MAKING THAT USE BRIDGE CURVE AND USE THROUGH CURVE MESH OPTION TO JOIN THE SURFACE
• THEN WE WANT TO MAKE THE OUTER SURFACE WE WANT TO MAKE THE LAW EXTENSION OF THE SURFACE OF UPTO TOP SURFACE OF 25 DEG AND 25mm OF SURFACE AND USE 2 TIMES OF TRIM SHEET OPTION TO TRIM THE SURFACE
• AFTER THAT WE WANT TO FILL THE LOWER SURFACE FOR THAT WE WANT TO USE SAME LAW EXTENSION WITH SAME VALES WE HAVE USED IN UPPER PORTION THAT MAKE THE BRIDGE CURVE OPTION
• FOR THIS SURFACE WE WANT TO USE THE SUDION SURFACE THIS SURFACE USE TO FILL THE LARGER SURFACE SO WE USE THE SURFACE TO FILL IT
• IN THAT THRE WAS SAMLL GAP IN IT FOR THAT WE WANT TO EXTEND THE TWO SURFACE AND USE TRIM OPTION TO TRIM THE SURFACE

ii)RENIFORCEMENT:

• AFTER MAKING THAT WE WANT TO MAKE RTHE RENIFORCEMENT TO THAT SURFACE FOR THAT WE WANT TO TAKE OFFSET OF 3 SINGLE SURFACE OF 10mm TO UPWARD OF THE SURFACE
• THEN USE OFFSET OF CURVE OPTION TO OFFSET THE SURFACE THEN WE WANT TO MAKEW TRIM THE SHEET OPTION TO TROM THE SURFACE THERE SOME EXTRA PORTIONS IN IT FOR THAT WE WANT TO TIM THE SURFACE
• FOR THAT WE WANT USE BRIDGE CURVE OPTION TO CUT THE SURFACE AFTER CUTING THE SURFACE USING TRIM SHEET OPTION USE FACE EILLET OPTION TO FILLET THE SURFACE
• THEN WE WANT TO JOIN THE SURFACE.NOW WE WANT TO SMALL RENIFORCEMENT IN THE SURFACE FOR HINGE,VINSHEILD,SIDE HINGE
• FOR THAT WE WANT TO SKETCH THE SURFACE AFTER THAT WE WANT TO MAKE EMBOSS OF THE SURFACE AND TRIM SHEET TO TRIM THE HOLE IN IT
• AFTER FINISHING THAT WE WANT TO FILLETS TO EACH OF IT WITH EITHER FACE OR EDGE FILLE IN TWO WANYS INNER AND OUTER SURFACE

iii)HEMMING SURFACE:

• AFTER FINISHING THE OUTER PANNEL AND INNER PANNEL WE WANT TO MAKE THE HEMMING SURFACE FOR THAT WE WANT TO OFFSET THE TWO UPPER AND LOWER OUTER PANNEL
• MAKE OFFSET OF 0.75+0.75+0.75+0.2+0.2mm DOWNWARD SURFACE AFTER OFFSET THE SURFACE TAKE OFFSET CURVE ON SURVACE OF 7mm INSIDE THEN USE TRIM SHEET TO TRIM THE SURFACE
• AFTER TRIM THE SURFACE USE SWEPT OPTION TO MAKE THE SURFACE AND GIVE SOME RELIEF TO THE SURFACE AND SWE THE SURFACE

DRAFT ANALYSIS:

AFTER FINSHING THE SURFACE WE WANT TO CHECK WITH THE DRAFT ANALYSIS.BECAUSE WHILE MANUFACTURING IT WILL CAUSE SOME TROUBLE TO IT.WHILE CHECH THE DRAFT ANALYSIS THE SURFACE SHOULD BE IN GREEN COLOUR.IT IS OK FOR THE MANUFACTURE
