摘　　要：控制棒驱动机构步进运动由钩爪组件的提升衔铁在竖直方向上升和下降的交替运动实现。通过对控制棒驱动机构步进运动进行分解,采用有限元方法建立电路-磁路-机械运动耦合的动态计算模型,对控制棒驱动机构步进运动过程中电磁力、电流、位移和时间关系进行研究,得到步进运动的提升时间、下降时间、衔铁吸合时电流和电磁力等运动特性参数。The step motion of control rod drive mechanism is accomplished through the lift armature of claw assembly hoisting and falling alternation movement in the vertical direction. In the base of the control rod drive mechanism step motion decomposition, the dynamic calculation model of coupled magnetic-electric-mechanical movement is established by finite element calculation method. The relations between magnetic force, electric current, displacement and time are studied in the process of control rod drive mechanism stepping motion. The movement characteristic parameters as hoisting time, falling time, electric current and magnetic force are obtained. The results can be applied to the time sequence design of control rod drive mechanism.
