Good morning Sir n Mam

I have created a 0D CBUSH element for Resonance Stress Analysis. But in my analysis Cbush element is not showing it's spring behaviour. It seems like nodes  of CBUSH element is not properly assigned to local coordinate system.

 

I am mentioning my procedure to create CBUSH element. Please correct me if I am wrong.

 

User profile - MSC NASTRAN

Analysis -> Systems->Node by reference> Create

 

1D -> Cbush->node 1&2 selected(coincident)-> system-> select coordinate system for cbush element-> create

 

Analysis -> System-> Assign -> select nodes of cbush element--> set displacement.

    In spring panel there is an option at bottom named Orientation, if you scroll that then you get an option named SYSTEMS

    Ok. I think you don't need to assign disp system for the nodes

     

    Tell us why you are sure that cbush is not showing spring behaviour?

     

    How about PBUSH settings? Could you show this card?
