First of all, I would like to thank everyone for the input. The thing I am concerned about is the system might be over-damped even with no current applied to MR damper.Because MR dampers are known to have a pre-loading damping force. Regarding the excitation, I am using an inertial shaker so I...
Sorry I forgot to attached the file in my previous email (see the attached)http://files.engineering.com/getfile.aspx?folder=34ccd8c0-aaa5-4490-b4ab-ef158609665b&file=forum.bmp
Many thanks guys for your help and sorry about my late reply.To start with my system is a sdof system isoalton system with mass supported by srpring in parallel with an MR damper (see the attached).
The magnitude of disturbance fore applied at the top of the system (i.e mass) is about 100N...
Mnany Thanks, your help is very much appreciated. I thought before the disturbance force must be large enough if the stiff is very stiff
Kind Regards

Hi guys
I would very much appreciate if someone can help me answer this question. In sdof vibration isolation system with very stiff spring does the system still resonate at the resonant frequency region even if the disturbance force is very small
Many Thanks
