摘要
控制棒驱动机构(CRDM)是关系到反应堆正常运行和安全可靠的重要设备之一。控制棒驱动机构普遍采用磁力提升式结构,其中电磁设计是驱动机构设计中的一个核心内容,也是保证机构安全、稳定运行的关键技术。针对这一关键技术研究,对ANSYS有限元程序和分析方法进行验证,论证用有限元分析电磁场的可行性。根据核电站驱动机构磁路计算书中提供的输入,分别计算控制棒驱动机构提升磁路、保持磁路和传递磁路等三个磁路的电磁场;并分析控制棒驱动机构整体磁路的电磁场,计算提升磁路与保持磁路电流方向相同、方向相反和提升磁路单独通电等三类情况。
The control rod drive mechanism （CRDM） is one of the key equipment related to reactor normal operation, safety and reliability. The CRDM structures often use magnetic jack type. The electromagnetic design is a core content in the CRDM design and key technology to ensure mechanism safe and steady operation. Based on the key technology research the ANSYS program and analysis method are verified, and the feasibility of electromagnetic field analysis with finite element is validated. According to the inputs of calculation manual for CRDM, the electromagnetic fields of lift, movable and stationary magnetic routes are computed. The electromagnetic field of CRDM integral magnetic route is analyzed. The three cases, which the current direction of lift magnetic route is uniform and opposite as the movable magnetic route＇s, and which the lift magnetic route is electrified alone, are computed.
