Hi all, I have a ground excited single degree of freedom model, like that:
http://www.bsw-schwingungstechnik.de/fileadmin/user_upload/images/2/graphic-passiv-isolation.jpg
I know the excitation function, i.e. s(t), but I need to know the force that imposes a specific s(t). I need it, because I want to simulate a model (little bit more complex) with a multibody tool, that it doesn't allow to excite systems with a ground displacement. So I need to convert the ground excitation with an equivalent force excitation. How could I do that for the single degree of freedom model? Any suggestion is appreciated.
Hopefully the problem is well stated.
thanks
Cheers
Pietro
