| Abstract: | Based on the complex modal analysis and the evolutionary spectrum analysis, a practical method for finding the time dependent m.s. response of a time invariant linear system subjected to common source evolutionary random excitations is suggested in this paper. As an example, through a simplified model the ground induced nonstationary random response of a vehicle travelling with varying speed is obtained by the method. |
