摘要
为确保控制棒驱动机构的设计合理性和先进性,利用ANSOFT软件对控制棒驱动机构的工作磁路进行了电磁场有限元计算分析。根据核电站工程项目驱动机构的相关设计输入,分析控制棒驱动机构整体磁路的电磁场,并以提升磁极输出电磁力为例,计算分析提升线圈单独通电、提升线圈与移动线圈同时通电和提升线圈与保持线圈同时通电3种工况下提升磁极的力移特性。分析结果表明,采用的仿真分析方法可靠、准确,可用于控制棒驱动机构电磁结构的优化设计或适应性设计中,并可配合解析方法使用,提高了驱动机构设计的合理性和先进性。
In order to ensure the rationality and advancement of control rod drive mechanism(CRDM),it presents the electromagnetic finite element analysis for the magnetic circuit of CRDM in ANSOFT.Based on the design input of the nuclear power plant,the electromagnetic field of whole CRDM magnetic circuit is analyzed.The example shows the lift pole outputting electromagnetic force,force-movement characteristics under three operating conditions.It analyzes the lift coil turning on,lift coil and moving coil turning on,lift coil and keeping coil turning on.The results show that the simulated analysis is reliable and accurate and the method can be used for the optimal design or adaptive design.
