摘要
反应堆压力容器检查机的支撑腿结构起定位和支撑作用,其结构的合理性对反应堆压力容器检查机的定位精度和可靠性具有重要影响。针对第三代核电站EPR堆型核反应堆压力容器结构,设计了具有自动定心功能的支撑腿结构。采用有限元方法分析了支撑腿结构的可靠性,并进行了验证力学试验。试验结果印证了相关理论分析结果,证明该支撑腿结构的设计是合理可行的。
The support legs are the positioning and support functional components of the Reactor pressure vessel inspection equipment ~EPR CIME）. The rationality of the structure has important influence on the positioning accuracy and reliability of EPR CIME. According to EPR nuclear reactor pressure vessel structure of the third generation nuclear power plants, the support legs were designed with the function of automatic centering, and the reliability of the support legs was analyzed by using ANSYS method, then a mechanics experiment was carried out. Mechanics experiment verified the theoretical analysis results, and proved that the design of support legs were reasonable and feasible.
