In this paper, a method USES to calculate structure dynamic response is proposed, which is based on the three parameter reliability model and perturbation probabilistic finite element method.

将可靠性分析三参数法与摄动概率有限元法相结合，提出了一套求解结构体动态响应概率分布的方法。

By optimizing the probabilistic weighted synthesised linear quadratic performances for different states of parametric uncertainties, the unity design in the parameter space is achieved.

通过对系统的不同参数摄动状态进行概率加权综合二次型指标寻优，实现了整个参数域的一体化设计。
