摘要
在非平稳激励下,讨论了结构的动力可靠性:对响应为高斯分布时,给出了以概率乘积形式表示的可靠度表达式;对更广泛的分布形式,文中利用有序统计和极值理论,给出结构响应的可靠度简化计算方法.并以某类继电器为例,计算了继电器接触系统的动力可靠性.
This paper discusses a computation method of structure dynamic reliability under unsteady excitation. It gives the reliability expression in the form of probability multiplication when the response follows Gauss distribution. To the more extensive distribution condition, the paper adopts the theory of ordered statistics and the extreme value theory, and gives a simplified computing method of structure response reliability. Finally, it computes the dynamic reliability of a relay contact system as an example.
