摘要：

The response of a rectangular plate subjected to nonstationary random load is studied. The general expressions for the autocorrelation and the mean square displacement are derived and discussed. Similar study was carried out for the stress components. The random excitation is then assumed to be a modulated white noise or narrow-band process. It is shown that when the damping coefficient is small, simple approximate expressions can be obtained for the variances of the lateral displacement as well as the stress components. Several examples using a simply supported plate are presented. © 1979, Acoustical Society of America. All rights reserved.
