| 摘 要： | 目前,对单自由度非线性振子受随机激励的响应计算已经发展到了多种方法。本文从白噪音与泊松过程的联系出发,把系统受白噪音或调制白噪音激励的响应计算转换为对泊松随机脉冲激励的响应计算,从而发展了一种数字模拟方法。此法与其它模拟计算方法所得结果有良好的一致性,并具有较高的计算效率。

| Abstract: | There are various algorithms available in the literature for the digital simu-lation of nonlinear systems excited by random disturbances.In this paper a digitalsimulation approach is presented for the determination of response of nonlinearsystems subjected to stationary or modtulated white noise excitation.It is based onthe relationship between white noise and filtered poisson processes.It is more ac-curate and efficient than some existing digital simulation techniques. |
