| Abstract: | This paper presents the analysis of the response of dynamic systems to stochastic excitation with time lag by a state space method on time domain. The method is suitable for random excitation both in stationary and nonstationary cases, and its application could be extended to nonlinear analysis when the equivalent linearization technique is introduced. Two application examples are given, namely response of long--span struetures under stochastic tranversely propagated earthquake motion and vibration analysis of vehicle motion. The proposed method is suitable for uso on common computers. |
