Abstract:

Simple cases were analyzed for a one-dimensional linear chain, and OHara 1 for a duel-foundation shipboard equipment. The report includes the analytical presentation of this method, the physical interpretation of the entities derived, the technical method suggested in taking and analyzing test data and drawing conclusions, and the extension of its application to damped systems, which is of importance in engineering practice. Various computer simulations of a problem designed to illustrate the developed method are provided.
