摘　　要：为了分析机械参数对水轮机筒阀多缸同步运动的影响,进行了筒阀多缸同步系统的动态仿真.在分析筒阀多缸同步系统的工作原理及控制策略的基础上,选择筒阀开启过程作为仿真对象,运用AMESim软件搭建了筒阀的物理模型并设置了模型的主要参数,分析了机械参数对系统动态特性的影响.仿真结果表明:接力器的负载不均、缸径制造误差和内泄漏导致系统最大同步误差变大;管道的通径和类型的变化,使筒阀运动行程的始末端的速度产生较大波动;同时管道长度的增加以及竖直管道的存在,导致系统的速度响应产生一定的滞后.To analyze the impact of mechanical factors on multi-cylinder synchronous motion of ring gate for hydraulic turbine, dynamic simulation for multi-cylinder synchronous system of ring gate was implemented. Based on the analysis of the operation principle and control strategy of multi-cylinder synchronous system, the opening process of ring gate was selected for simulation. The model of multi-cylinder synchronous system was established by AMESim software and the mechanical parameters were set, and the impact of mechanical factors on system dynamic characteristics was analyzed. The simulation results illustrate that the maximal synchronization error was affected obviously by uneven load, cylinder diameter error and internal leakage of hydraulic cylinder, and the velocity fluctuation was affected by the change of pipeline diameter and type. Meanwhile, the increase of pipeline length and the existence of vertical pipelines would result in response lag of velocity property.
