Week 6 - Creating connection for Rear door

Aim: To create PIDs & create different connections

Procedures:

1st assinged PIDS for different parts for that used Topo module - Faces - Set PID. By selection of perticular parts clicked middle click & then by right clicking created new P shell PID & by double clicking assigned to that part.

Then moved to create connections & firstely watched model cleary & understand the connection which need to give.

At door hinges created bolt connection for that used the procedure - Created COG point & then it converted to 3D point by using convertor selected point & by middle clicking choose Bolt option. Then By using connection selection assistent selected same 3D point & middle click, then it open Connection Manager & in it selected P1 & in modify gave command F1 & selected the bolt's 1st hole & same selected for P2 & selected 2nd hole. Then in FE representation setting selected type is Bolt & selected Zone as Inner & clicked Apply & Realize & the bolt is created.

At window of door need to do seam weld for rubber bidding for that created curves at outer edge of glass by using Mesh module - perimeters - feat2curve . & at bottom created another curve line & then all that curves created as curves by using convertor, but selected one by one & choose seam line. Then By using connection selection assistent selected same curve & middle click, then it open Connection Manager & in it selected P1 & in modify gave command F1 & selected the curve & same selected for P2 & selected 2nd connected object. Then in FE representation setting selected type is RBE3 CBush RBE3, gave search distace as per distance between 2 parts/curves (I gave 50) & RBE3 pinflange DOF made to 6, clicked on keep all branches, then in body Pbush created new Pbush ID by shift + ? & clicked Apply & Realize & the seam line is created.

Same procedures for spot weld just need to covert into spot weld & in FE representation choose type is RBE3 HEXA RBE3 & rest same.

For some holes created RBE2 rigid connection by using many nodes & also used loop for setection.

At Handle crated two RBE2 connections & gave mass for that by using CONMi in Nastran.

Learning outcomes: Learned how connection to be plotted & where.

Conclusion: Need to work more on it. I suffered liitle hard while placing connections like bolt, seam & spot.
