Week 6 - Creating connection for Rear door

Objective:-

For the given Rear door FE model, Create and Apply different PIDs for different components and perform suitable connections.

Procedure:-

1. Import the model
2. The imported model only consist of only F.E .
3. We can set different PIDs of the elements using set PID option. MESH>Macros>Set PID.
4. For bolt connection we have to create a COG point in hole where we want to use bolt. TOPO>Points>On COG>Select loop selection tool>Select the edges of the hole.
5. Now we convert the COG point into bolt type using convert option. Assembly>Convert>3D Points>Select the point>Connection type :- Bolt.
6. Now we have to go connection manager select the bolt, the connection manager window will appear then we set the value of P1,P2 and P3.Then set the FEA representation type as Bolt. Then set search distance =20 then click apply then realize.
7. Repeat the same for all the bolts.
8. For Pbush we have to create the curve. MESH>Parameters>Feat2Curve> select the curve using path selection option.
9. Now we convert the curve into spotline type using convert option. Assembly>Convert>Curve>Select the curve>Connection type :- Spotline.
10. Now we have to go connection manager select the spotline curve, the connection manager window will appear then we set the value of P1,P2 and P3 and S ( Spacing)= 10.Then set the FEA representation type as RBE3-CBUSH-RBE3. Then set search distance =20 and and create a new Pbush ID and select it then click apply then realize.
11. Repeat the same for all weatherstrips.
12. For hinges we have to create it mannually go to nestran deck then create two cluster RBE2s and then connect them using 2 noded RBE2. NASTREN>ELEMENTs>RBE2 (we will set the CM=12345 to constrain its motion).
13. For spot weld connection we have to create a COG point in element where we want to spot weld. TOPO>Points>On COG>Select loop selection tool>Select the edges of the element.
14. Now we convert the COG point into spotweld type using convert option. Assembly>Convert>3D Points>Select the point>Connection type :- Spotweld.
15. Now we have to go connection manager select the spotline curve, the connection manager window will appear then we set the value of P1 and P2.Then set the FEA representation type as RBE3-HEXA-RBE3. Then set search distance =10 and and create a new PSolid ID and select it then click apply then realize.
16. Repeat the same for all spot weld.
17. Now we have to create the con mass in door handle when we open the door there well be some weight added on it as a hand weight.
18. For this we have to create cluster two RBE2s and connect them using 2 noded RBE2.
19. Then we add mass on it using CONMi option. NASTREN>ELEMENTs>CONMi>select the nodes> then ass mass value of 10 units.

Conclusion:-

From this challenge we learned about 1D meshing and different type of connection.
