I can follow you by saying I just created a 2DOF system with two distinct natural frequencies that is excited at one of those frequencies. But that is what a TMD does, right? Turning a SDOF system into a 2DOF system and by doing so, reduce the SDOF system's response at it's natural frequency...

I agree, usually the TMD is tuned to the eigenfrequency of the structure. But in my case I want to mitigate the response at 0.6 Hz, and a TMD should be able to reduce any frequency as long as it is tuned to that specific frequency right? Best regards

Hello everyone, I have a simple question. Lets say a single degree of freedom system (SDOF) which consists of a spring and a mass is excited by an external force. The SDOF system has the eigenfrequency of 0.31 Hz and the external force is a periodic force with the frequency of 0.6 Hz. After...
