| 摘 要： | 针对压力容器制造、使用过程中各种参数的不确定性,提出了一种基于响应平面的随机分析方法.根据某压力容器的结构特点,确定性有限元分析采用了接触有限元,结合中心组合抽样设计构建了容器最大应力的响应平面,以此为基础对压力容器应力分布进行了随机分析.可靠性分析中引入应力—强度干涉模型,并分别对容器壁面和接管处进行了可靠性评定.实... |

| Abstract: | Aiming at the uncertainty of a variety of parameters during the pressure vessel manufacture and application,random analysis method based on the response surface is proposed.According to the structural features of pressure vessel,certainty of the finite element analysis using contact finite element is combined with central composite design to build a sample of response surface of container with the largest stress,which is used as the basis for random analysis of stress distribution of pressure vessel.The str... |
