Average Mechanical Impedance for Random Vibration [PDF]
The Journal of the Acoustical Society of America, 1972 The response of a system to a random stationary process applied at selected points of a mechanical structure is readily formulated in terms of the mechanical impedance matrix of these points. However, in practice the results suffer from many uncertainties: uncertainties in the measurements of the mechanical impedances; uncertainties in the boundary ...

Vibration control studies using an impedance method [PDF]
SPIE Proceedings, 2003 This paper presents a vibration control methodology that is useful in practical applications where the system to be controlled is difficult to model due to the presence of uncertainties or complex boundary conditions. The impedance control method uses a power flow approach wherein the controller is designed such that power flow into the structure is ...
