Impulse response for electromechanical coupling system on a distributed-parameter basis

The impulse response for an electromechanical coupling vibration system in a distributed-parameter basis is considered from the viewpoint of energy propagation in a transducer, and the comparison with conventional lumped-parameter-based methods is discussed. The method introduced in this study has some advantages over the conventional ones; for example, the present method (1) can reflect the behavior of energy affected by electromechanical coupling more correctly (2) can be applied at N degrees of freedom for elastic vibration, compared with the conventional ones that require 2N degrees of freedom and (3) can represent the dissipation (loss) phenomenon more reasonably.
