Week 4- Challenge

OBJECTIVE:

To creat 1D elements on the following component with given cross-section and DOF.

CAD MODEL:

PROCEDURE:

First i import the cad model
then i applied points on the entire model
then i converted those model to a wireframe model
to create midsurface go geometry and go and select the componeents to get mid surfase and extract.
then we go to component option and add a components inorded not to get a combined surface or ideal .
by adding a component we next find the midsurface of down bracket.
then we move the midsurface created to the created compunds using organise option in tool option
by selecting the surface to be moved and selct move option
and then it will change to the colour we given to the created compound
then we select the matterial on the topleft corner option
this will show the matterial details in down left cornerand defined
then we should assign the propertyto the matterialand name it
then made properties for all componet need to be specified
select the thicknessfrom down left corner and also selct properties and card image as optstruct.
and also select the matterial going to use
same to do with other component also
then we shound go 2D to automesh and select the meshtype as mixed
before which we want to give washersplit to the holesfrom quick edit washer split
and then we provide the offset value
then we go to 2D and go to automesh
then selct the surface and select displayed surface
and give it as mixed and mesh it

then i given rbe2 lynk in d and e holes and given mass to them with magnitude 10
then i given a, b , c with rbe2,rbe3,rbe3 links

i had done that with giving the dof for seperate a,b,c holes
also i given a spring in f bygoing spring option and selecting thole nodes.
then i given element connect betwen the holes parallel by going rod bar and bar for beam option
to create beams, rods and bars in cross section i select standard section in hyperbeam option and i select create option
then the scereen take us another page then we can create those 3 cross sections required by using create option go to standard section and go to optistruct or hypermesh inorder to create the cross sectins needed.

and give the dimension to the cross sections needed
then by giving the properties, matterial,cardimage,crosssection and all and then to update in the model

then we got a model with 3 crosssection, with rbe2,rbe3 link,spring attached and with mass respresented.

FINAL MODEL IMAGE:

RESULT:

Created 1D elements on the following component with given cross-section and DOF

a. Rod element:- with only translational DOF and RBE2 link

Cross-Section: BOX- Dimension a= 12 mm

dimension b=10 mm

Thickness t= 0.75 mm

b. Beam element:- with all DOF and RBE3 link

Cross-Section: I Section- Dimension a= 8 mm

Dimension b= 10 mm

Dimension c= 8.5 mm

Thickness t1= 0.75 mm

Thickness t2= .6 mm

Thickness t3= .6 mm

c. Bar element:- with only x and y DOFs With RBE3 link

Cross-section: CROSS section- Dimension DIM1= 5 mm

Thickness DIM2= 1.2 mm

Dimension DIM3= 10 mm

Thickness DIM4= 1.2mm

d. & e. apply the mass of magnitude 10 with RBE2 link.
