Week 6 - Creating connection for Rear door

Objective: To create and apply different PIDs for different components and to perform suitable connections.

Procedure:

1. Choose each of the parts by PID region and assign a new PID. (Topo module - Set PID)
2. Parallel holes have to be connected by bolt joint:
   1. Manual method: Create RBE2 clusture of elements from Nastran module - RBE2 - Many nodes. Create the clusted on the parallel hole too. Now join the master of two clustures with two noded RBE2 element.
   2. Automatic method: Create on COG point from Topo module with any of the holes. Convert the 3D point into Bolt connection (Assemply - Convert - 3D point - Bolt). Go to connection manager and select the bolt and define bolt connection with In/Out option.
   3. 
3. 
4. For the rotation, restrict degree of freedom to 12345
5. All other shapes of holes can be connected with rigid connections.
6. 
7. Seam weld has to be done for the following parts
   1. 
   2. Create curve by selecting the edges of the FE. (Topo module - Curves - Cons2Curves - Select the edges)
   3. Use Convert option and convert the curve to Seam line joint
   4. Go to connection manager and define deam weld between 2 parts with Overlap Shell joint
   5. Define width as element size
8. For spot weld - create COG point with parallel element
   1. Convert the 3D point to spot weld
   2. Connection manager - RBE3-Hexa-RBE3 - Pinflags to 123456
   3. 
9. Apply mass to door handle:
   1. Nastran module - CONMi
   2. 
10. Create PBush element for windows:
    1. Create curves around the window and 2 curves at the bottom
    2. Convert the curves to spot line
    3. Connection manager: S=10, RBE3-CBUSH-RBE3, all pinflags, new PBUSH element
    4. Give element property K1,K2,K3 = 0.001 K4,K5,K6 = 10
    5. Select PBUSH element form F12 - Edit the element to orient with chord and CID =0
    6. To do this for all elements, select all elements and modify with the same.
11. For Window mechanism, Create elements upto the window and RBE2 elements
12. 
13. Do the connections until, if we select a PID and give neighbour all then, all PIDs should appear.

Results: Connections has been applied to the components.
