Design and Analysis of Lifting Device for the Ring Chain of the Control Rod in High Temperature Gas-cooled Reactors

针对控制棒驱动系统故障处理需求,设计了圆环链提升装置辅助快速处理圆环链,实现控制棒驱动机构与控制棒的快速拆卸分离。为了避免圆环链及控制棒横向振动振幅过大,保证控制棒的安全以及圆环链的顺利提升,运用ADAMS建立了相应的虚拟样机模型,对圆环链和控制棒的振幅大小和振动规律进行了研究。物理实验和仿真结果表明,该装置可实现较小振动幅值下的圆环链提升过程,满足工程实际要求。

According to the fault handling requirements of control rod drive system,a lifting device is designed to assist the rapid lifting of the ring chain,so as to realize the rapid disassembly and separation of the control rod drive mechanism and the control rod.In order to avoid the excessive lateral vibration amplitude of the ring chain and control rod,ensure the safety of the control rod and the smooth lifting of the ring chain,the corresponding virtual prototype model was established by using ADAMS,and the amplitude and vibration law of the ring chain and control rod were studied.The physical experiment and simulation results show that the device can realize the lifting process of ring chain with small vibration amplitude and meet the practical requirements of engineering.
