PROBLEM TO BE SOLVED: To conduct behavioral analysis of transient and stationary vibration motions of a system, in which a spring attenuation factor having optional frequency characteristics and a spring attenuation factor, having optional nonlinear characteristics, coexists. SOLUTION: The program analyzes transient and stationary behaviors. The program applies Laplace transform on the transfer function H(ω) of an input displacement X(ω) and an output load F(ω), thereby obtaining function H(s) on a plane (s). The function H(s) is transformed into a function H(z) on a plane (z) by z-transformation of H(s). By performing inverse z-transformation of H(z), a recurrence formula expressing discrete time data of an input and an output is obtained. An equation of motion which utilizes the recurrence formula is subjected to time of day response analysis. COPYRIGHT: (C)2004,JPO
