为改善中国先进研究堆(CARR)控制棒驱动机构在转向过程中的跟随性能,对CARR控制棒驱动机构进行改进研究。根据CARR控制棒驱动机构结构和功能搭建试验样机平台,在试验样机平台上进行了极限载荷试验、线圈温升试验、系统刚度试验等,掌握了CARR控制棒驱动机构重要磁学和力学参数,为CARR控制棒驱动机构进一步改进提供了必要的参考数据。1)极限载承试验在通电电流小于2.0 A时最大提升力与电流基本成正比,在通电电流达到2.0 A时提升力达到
In order to improve the follow-up performance of CARR control rod drive mechanism during steering, the CARR control rod drive mechanism was improved. According to the structure and function of the CARR control rod drive mechanism, a prototype platform was set up. The ultimate load test, the coil temperature rise test and the system stiffness test were carried out on the prototype platform. The important magnetic and mechanical parameters of the CARR control rod drive mechanism were grasped as Further refinements to the CARR control rod drive provide the necessary reference data. 1) Ultimate load test When the current is less than 2.0 A, the maximum lifting force is basically proportional to the current, and reaches the 2.0 A when the current reaches to reach the lifting force
