Determining damping capacity of a damper

Hi,

I have a question about non linear dynamic analysis.

I have a damper like the one shown on attached PDF. There are metal components, and some rubber components, and there is contact.

 

Can SolidWorks Simulation predict damping capacity of the damper ?

 

A linear dynamic harmonic analysis could give this answer by working in frequency domain.

 

In non linear dynamics you work in time domain, and you could get that info by applying an impulsive load and looking at the response of the damper.

This way you can account for all non linearities (rubber, contact, and so on).

 

But would simulation really give you that info ?

I was thinking about the fact that you have to introduce Raleigh Damping parameters, which you should know by testing the model.

If I think about that it's like I'm simulating something, but I'm already introducing the answer I'm lloking for in the system (i.e. damping).

 

Thanks,

 

Alex
