1D spring stiffness

Recommended Posts

Hi All,

 

I want to create spring element for my model. I have created using spring section in hypermesh and used CELAS1 element. I need to define Spring stiffness. For that I have used Property with Spring gap type and PELAS as a card image. Here comes my problem, I need to give 10N/mm stiffness to spring. In property card whatever values I give it to K column, the displacement is same. It is not taking as stiffness. I do not know how it is calculating or  any thing I have missed. Please help me on this?

Hi Udhay,

 

I tried on a simple CLEAS1 element and as the stiffness changes I see change in displacement. 

 

Can you share the model file with us?

Have you made a Local coordinate system for the spring and then make the dof update for spring in the same direction of its axis. This should work I think.

I think this may help. Maybe the orientation is an issue with the CELAS element in your element.
