Dynamic Analysis of CRDM Loads during Stepping Motion

摘要: 通过动力学分析和Adams动态仿真,对中国改进型百万千瓦级压水堆(CPR1000)压水堆控制棒驱动机构(CRDM)步进载荷进行计算。结果表明,通过Adams动态仿真可以得到CRDM提升过程和下插过程中钩爪、销轴、可拆接头等部件的步进载荷值,所得值与工程经验相符;提升和下插过程中最大步进载荷出现在可拆接头处;同时销轴的步进载荷值较大,应注意销轴的材料选择与设计;水力缓冲对下插步进运动有重要的缓冲作用,能够减小下插过程的步进载荷。

Abstract: CRDM stepping loads act on the parts of CRDM during stepping motions. In this study the CPR1000 CRDM stepping loads are calculated through kinematics analysis and Adams dynamic simulation. The stepping loads of latch, pin, and coupling are got. Conclusions show that the method is an effective method to calculate CRDM stepping loads and the results are consistent with engineering experience. At the same time comparison and analysis of the impact of hydraulic camping force on insertion motion are studied.
