Abstract : Limitations on the practical application of the inverse eigenvalue method are discussed. The principle of dynamic equipollency, which is derived and related to the limitations of the inverse eigenvalue method, makes possible an efficient method of dealing with a structure having many degrees of freedom. It is also shown that moment-rotational velocity impedances can be generated experimentally using the principle of dynamic equipollency. (Author)
