| 摘 要： | 应用ANSYS有限元程序,采用蒙特卡洛法中的直接抽样法和拉丁方抽样法、响应面法中的中心指数设计抽样法和Box-Behnken矩阵抽样法完成反应堆压力容器强度可靠性分析,给出指定输入条件下压力容器强度的可靠度。结果表明,对压力容器母材可靠度的影响程度由大到小依次为内压、母材许用应力和母材弹性模量;对主螺栓可靠度的影响程度由大到小依次为螺栓材料许用应力、螺栓预紧力和内压。

| Abstract: | This paper performs the reliability analysis of reactor pressure vessel(RPV) with ANSYS.The analysis method include direct Monte Carlo Simulation method,Latin Hypercube Sampling,central composite design and Box-Behnken Matrix design.The RPV integrity reliability under given input condition is proposed.The result shows that the effects on the RPV base material reliability are internal press,allowable basic stress and elasticity modulus of base material in descending order,and the effects on the bolt reliability are allowable basic stress of bolt material,preload of bolt and internal press in descending order. |
