CRDM钩爪组件缓冲轴的动力学分析

Dynamic Analysis on Buffer Shaft of CRDM Latch Assembly

采用理论结合试验的方法,对控制棒驱动机构(CRDM)缓冲轴在驱动杆下插时所经历的续流、剩磁、水力缓冲以及最后的撞击过程进行动力学分析,计算出缓冲轴在与保持磁极发生撞击时的初速度和平均冲击加速度,为CRDM缓冲结构的设计及强度校核提供准确和可靠的输入参数。

This paper conducts a theoretical and experimental dynamic analysis on CRDM buffer shaft subjected to the follow current, the remanence, hydraulic buffer and the final hit during the insertion of the drive rod, and calculates the initial velocity and average hitting acceleration when the buffer is hitting with the preservation magnetic pole, to provide accurate and reliable input parameters for the design and strength check of CRDM buffer shaft.
