摘要

研究了渐硬恢复力刚性滑移结构在水平和竖向高斯白噪声地面作用下稳态响应的概率分布问题。以等效线性恢复力刚性滑移结构代替原系统并利用等效非线性系统法推得了替代系统稳态响应的联合概率密度函数解析解;最后通过蒙特卡洛模拟结果说明了本文所提方法的适用性。
The probability distribution problem of the steady-state responses to horizontal and vertical Gaussian white noises of rigid sliding structures with hardening restoring force is studied in this paper. The original system is substituted by the one with equivalent linear restoring force, and the analytic solution of the joint probability density of the steady-state responses of the equivalent system is derived by means of the equivalent nonlinear system method. The applicability of the present method in the paper is exemplified by the results of Monte Carlo simulation.
