摘要:
通过对可靠度分析的概述理解到现代工程分析中实体模型不确定因素众多,进而带来分析的不准确性。基于有限元分析软件ANSYS提供的概率设计系统(PDS)的概率分析功能，使对结构的概率分析非常容易。根据结构的失效模式来确定结构功能函数,由此建立结构极限状态方程,再运用结构可靠度分析中的蒙特卡洛法(MCS法)利用结构的失效频率来估算其失效概率。在本文中提出了利用ANSYS的概率分析功能结合MCS法进行结构的可靠性分析的方法，并通过一个实例具体说明了利用ANSYS的概率分析功能实现结构的可靠性分析的可行性。
Abstract:
Through the over view on reliability analysis as a modern engineering analysis， it was known that there are many factors, such as material properties, processing tolerance, boundary conditions and loading, etc, can make analysis not accuracy. Design and analysis of structure engineering contains many uncertainty, engineering of the factors of uncertainty and random characteristics description is the basis of reliability analysis. Structure reliability evaluation of the reliability of the structure is index. The probability analysis is that our analysis the model on some of the input parameters and uncertainty on the assumption of the influence on the result of the analysis, and the results can be judged, it can improve product quality and reliability when it can't completely eliminate input parameter uncertainty. The software of FEA (Finite Element Analysis) ANSYS provides the function of probabilistic design of PDS, which makes structural probabilistic analysis very easy. According to the structural failure mode to determine the structure and function, thereby a structure limit state equation can be set up, again with the structure reliability analysis of the Monte Carlo method (MCS method), structure failure frequency can be used to estimate the failure probability. In this paper, the technique of the structural reliability analysis through the probabilistic design of ANSYS was presented. From an instance, it showed that the method presented is feasible.
