Summary:控制棒驱动机构是核电厂中的重要安全设备。其步跃动作的运行参数包括提升负荷、步距、步速等都是其核心设计指标。本文考虑重力、电磁力、水阻力和弹簧力载荷,建立了步跃运动方程。分别使用有限元方法和解析方法对步跃动作进行了动态模拟分析,获得了包括提升力、速度等时程变化曲线在内的结果,同时讨论了这些结果对设备设计的积极意义。
Bibliography:Background: Control rod drive mechanism (CRDM) is one of the important safety-related equipment for nuclear power plants. Purpose: The operating parameters of stepping movement, including lifting loads, step distance and step velocity, are all critical design targets. Methods: FEA and numerical simulation are used to analyze stepping movement separately. Results: The motion equations of the movable magnet in stepping movement are established by load analysis. Gravitation, magnetic force, fluid resistance and spring force are all in consideration in the load analysis. The operating parameters of stepping movement are given. Conclusions: The results, including time history curves of force, speed and etc, can positively used in the design of CRDM.
