Modelling Stiffness with curves

Altair Forum User

Hi,

I need to model the translational stiffness of a joint with a curve. It is possible to choose, inside the panel, the independent variable.

What I have to model is that my joint has to deform in relation of the force that the other bodies transfer to this. Should I change the Independent variable and set the force as the variable?

Thanks for the help

Hello Stefano - I believe you need to create a curve entity that represents the force v/s deflection behavior of the joint (compliant joint). Once the curve is defined, you need to refer it in the 'Curve' collector (the yellow button seen in the panel above). The independent variable of DX is correct.

I have attached an example and demonstrated how the curve is defined as well as the joint. only difference is that the nonlinear force-deflection is represented in Z direction of the joint. (not the model)

 

Hope this helps
