    Tuned mass damper does not reduce the amplitude of vibration?

    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...

    Tuned mass damper does not reduce the amplitude of vibration?

    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

    Tuned mass damper does not reduce the amplitude of vibration?

    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...
