Week 6 - Creating connection for Rear door

Aim: To do connections wherever required in the side door geometry.

Procedure:

Import the FE model.
Check for bolt,c-bush,spot weld, seam weld and hinge connections in the FE model.
Connections are done to ensure force transmission during simulation.
Bolt Connection: Check for parallel holes in the FE model.
Create a COG point across the hole.
Convert the COG point to 3D point to bolt using convert option.
Select the bolt using connection manager.
Select the PID's in connection manager tab
Select the FE representation as bolt and give appropriate search distance
Apply and realise the bolt, do the above procedure for all bolt areas.
Hinge: Use manual method for Hinge.
NASTRAN DECK<elements<RBE2 cluster for a holes
Connect the RBE2 clusters using two noded RBE2
Reduce the DOF to 1 to allow the door to open and close.
Do the above procedure for all hinge areas.
C-BUSH: Create curve along the geometry.
Convert the curve to spot line in connection manager.
Assign PIDs in the connection manager.
Select FE type as RBE2-CBUSH-RBE2
Give appropriate search distance and spacing values.
Give apply and realise.
SPOT WELD: Select element and create COG point.
Convert the COG poitn to spot weld.
Give property IDs, FE representation type (RBE2-HEXA-RBE2).
Give search distance and apply and realise.
Above mentioned are methods to create connections in the geometry.
BOLT CONNECTION

CONCLUSION: Therefore the given FE model is checked for all requirement and connected using connection manager in suitable area.
