Week 4- Challenge

OBJECTIVE:

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

CAD MODEL:

PROCEDURE:

Import the CAD model
Apply points on the entire model.
Convert the model into a wire frame model.
Go to geometry and select the components to get the midsurface and extract to create a midsurface.
From component option add a component to not get an ideal or combined surface.
After adding a component find the midsurface of the down bracket.
Move the newly created midsurface to the already created component using organise option from tools.
Mark the surface to be moved and select move option.
Change in colour occurs resemblance to the already created compound.
Select material from the top left corner.
Material details are defined in the down left corner.
Assign properties for the material and name it.
Assign properties for all the materials that need to be specified.
Assign thickness from the down left corner.
Select properties and card image as opstruct.
Select the material we are going to use.
Repeat same procedures for the other component too.
Mark washersplits around all the holes from quick edit- washersplit option.

Provide the offset values
Select the displayed surface entirely.
Select the meshtype as mixed and do the automesh.
After meshing make the nodes around the washersplits equal.
Hide the surface.
Provide RBE2 lync on d and c holes and apply mass of magnitude 10.
Then provide a,b and c with RBE2,RBE3 and RBE3 lincs with required DOF for each holes.

Apply spring on f holes from spring option by selecting the required nodes.
Create beam rod and bar in cross section by selecting create option from standard section in hyperbeam.
Another screen comes where to create required cross sections by clicking create option-standard section-optistruct or hypermesh.
Apply the provided dimensions to the cross sections.
