Design of backdoor

VVishag V13 May 2022

It consists for outer panel, inner panel, hinge reinforcements , gas stay reinforcements , wiper motor reinforcement, latch reinforcement

both aluminium and steel used to manufacture the back door , most of parts create by aluminium

PARTS:-

outer panel:

it is the styling surface of back door

it is the source of designig the other parts

its the outer cover of back side of car

inner panel:

it also provide the strength of outer panel

inner panel has reinforcements and embosses to stregthening

gas stay , hinge , latch , wiper motor reinforcements are connected ti the inner panel

hinge reinforcements :

its enable the opening and closing of the back door

hinge fixed on the back door and other end of roof panel

its used to aline the latch and trajectory of back door opening and closing

gas stay reinforcement:

gas stay device used to support the back doorin its open position

gas stay in engaged position into support position automatically open s the bck door

latch reinforcemeent:

its used to lock the back door with car

wiper motor reinforcement:

lts used to strengthening the back door

PROCEDURE:-

INNER PANEL:

open the given bac door model in the nx cad

extract the given surface in to 2 parts

one surface makes in the part folders a name outer panel upper

and other surface makes in the part folder as name outer panel lower

make other 2 part files as empty as the name of hinge reinforcement LH na RH

make 2 part files as empty as the name of gas_stay reinforcement LH na RH

make part file as empty as thr name wiper motor reinforcement

make part file as empty as thr name latch reinforcement

make the another part file as in extract the given surface in to 2 parts , as name innr panel

all prt files are in the back doof assembly

the 2 surfaces are enter in to the inner part file as usinng wave geometry linker

and make the features group for linke faces as name refferene geometry

then make the tooling direction by using intersectline in the maked 2 lines as outer side

extrect the outwr panel ones and make feature group as working surface

offset the faces at 1.7mm distace

make line by using offset line in face

bride curves used to connect lines

trim the extra side of sheet by using trim sheet

untrim the back tail of outer surface and make lines by using offset in face at correct valve

trim the the extra portions

bride curve used to connect both surface and make surface by using throughcuve mesh

offset the suface at required length

make linke by using offset in surface

trim the sheet at required length

bridge curve used to connect both surface and make surface between them

sew all sutfaces

extracted the sew surface

law extend the surfce at given distance at angle of tooling direction

extract the law extruded surface and apply the face blend

extract the upper and lower outer panel

trim and extend used to make 2 surfaces trim perfectly

connect 2 surfaces by using bridge curve and makes surfaces between them

connect 2 surfaces by using bridge curve and makes surfaces by using studio surface

apply trim sheet to trim extra surface

sew all surfaces and apply edge blend

then extract the surface

then apply face blend in 2 adjesent sides

make features group as connecting blends1

extract he blended surface and then extend the sheet

apply low extension at ends in the tooling direction

trim the upper sides properlly and trim top surface properlly

then low extend same way of above create surface

make line properly to cut the surface

then make the bridge curve to make the between surface correctly by using studio surface

make top surface by using bridge curve and studio surface at the bottom side of panel

then extend the sheet and trim all extra portions

apply face blend on the edege

extract the body ones

make another feature group aas wind sheild

make sketch for tail tailight ebmoss

ebosses the sketch upward upto 10mm

apply blends on the edges

make offset line in top surface and trim it

make sketch for tail y shape ebmoss

ebosses the sketch upward upto 10mm

apply blends on the edges

make a plane for hinge reinforcement

make line at an angle then low extrude the surface at required length

law extrude 4 sides upward an sew all makes surfaces

trim and extend used to make emboss structure

edge blend apply on the all edges

make hole at centreby using trim sheet

make a plane for gas_stay reinforcement

make line at an angle then low extrude the surface at required length

law extrude 4 sides upward an sew all makes surfaces

trim and extend used to make emboss structure

edge blend apply on the all edges

make hole at centreby using trim sheet

make sketch on the wiper_motor reinforcement

emboss create at 10mm distance

edge blend apply on the all edges

make hole at centre by using trim sheet

extend all sides at 10mm and trim by mirroring plane

sew all surfaces as sheet

mirror the sew surface by using x-y plane as mid plane

make the mid piont of LH and RH and connects to make a line

make a plne at the cente of line and make a cricle at center of line

make a plane for yatch reinforcement

make line at an angle then low extrude the surface at required length

law extrude 4 sides upward an sew all makes surfaces

trim and extend used to make emboss structure

edge blend apply on the all edges

make hole at centre by using trim sheet

thicken the inner pane1 at 0.75 in upward direction

OUTER PANEL UPPER:

offsed the surface at 2.65mm in down ward direction

make a offset line upto 12 mm and trim the inner side portion

at the corner make a sketch by using curve on surface

trim the surface at u shape

make bride curve on the both sides by using 2 surfaces edges

swept commad used to make the corner surface

when the side of not showing proper swept , then cut smaller portion of swept surface and make a new stutio surface bridge curve

sew all surfaces

extend the outer side of all surface and trim at refference of mirroring plane

mirror all surface at x-y plane refference plane

sew all surfaces ones

thicken the sew sufaces at 0.75mm downward direction

OUTER_PANEL_LOWER :

offsed the surface at 2.65mm in down ward direction

make a offset line upto 12 mm and trim the inner side portion

at the corner make a sketch by using curve on surface

trim the surface at u shape

make bride curve by using 2 surfaces edges

swept commad used to make the corner surface

sew all surfaces

extend the outer side of all surface and trim at refference of mirroring plane

mirror all surface at x-y plane refference plane

sew all surfaces ones

thicken the sew sufaces at 0.75mm downward direction
