摘要

介绍了核电厂主管道自动焊组对的重要性和存在的组对风险,以主回路焊前组对情形为研究对象,提出尺寸链封闭算法,幵根据工程实际设定了初始值、约束条件和优化目标值,实现了主回路焊接组对情况的预判功能,同时进行了设计验证与工程验证,验证结果与工程实际相符。
        The importance of the fit-up of reactor coolant pipe and its risk were analyzed. Focused on the fit-up situation of the primary piping, this paper proposes an algorithm for the close fit-up dimension chain, and the initial value, constraint value and optimization value were set according to actual engineering. The predicting of the fit-up situation was realized. Meanwhile, this algorithm was tested and verified by theory and engineering. The result is consistent with the actual value.
