Wykorzystanie analizy modalnej do badania układów dynamicznych o wielu stopniach swobody

Władysław Lisewski, Paweł Gutowski

An approximation method for experimentally determined amplitude-phase-frequency characteristics, of complex mechanical systems has been presented. On the basis of modal parameters describing particular set of characteristics and obtained from the approximation, the method has been shown of stiffness and damping identification for the examined object. The introduced algorithms made it possible to develop a system of programs. The examples prove the correctness of presented method, and indicate the possibility of applying the method for examining real dynamical systems.
