控制棒驱动线落棒行为动力学仿真技术研究

摘要

In a pressurized water reactor,the control rod drive line (CRDL) controls and protects the reactor.The paper uses the virtual prototyping technology to simulate rod dropping behavior.It shows the detail about some factors such as the fluid-solid coupling,rigid-flexible coupling,mechanical friction and collision.It an-alyzes the results between simulation and experiment,verifies the method and technology.%反应堆控制棒驱动线是反应堆控制与核安全保护的执行机构.应用虚拟样机技术,进行了控制棒驱动线落棒行为动力学仿真研究.通过合理处理驱动线落棒过程中的流固耦合、刚柔耦合以及摩擦碰撞问题,获得了动力学仿真在驱动线上应用的方法和技术.仿真结果与实验数据对比表明,研究得到的方法合理可行.
