摘要
利用Ansys概率设计模块PDS,通过选取合适的随机输入参数,利用蒙特卡洛法对核电厂安全壳贯穿件和某压力容器抗震支架进行了可靠性分析,获得了结构在输入参数不确定情况下的可靠度和概率分布规律,以及输入参数对输出结果的灵敏度等信息,直观地显示了输入参数对输出结果的影响,为可靠性分析在核电厂结构设计中的应用提供了有价值的探索。
By using the PDS of the Ansys probability design module and choosing appropriate random input parameters, a reliability analysis is made in this paper on the containment penetration and the seismic support of a certain pressure vessel by the Monte-Carlo method to obtain the reliability and probability distribution of the structure when the input parameters are uncertain, and the sensitivity of input parameters to the result; and it visually displays the influences of the input parameters on the result. This paper provides a valuable exploration for the application of reliability analysis in the,structure design for nuclear power plants.
