摘　　要：设计了垂直冲击试验台液压控制系统;建立了系统模型并仿真分析了垂直冲击试验台闭环位置控制系统的稳定性、快速反弹制动性能和同步特性。研究结果表明,垂直冲击试验台液压系统采用液压泵和蓄能器组合动力源,可满足同步控制时的流量需求和快速夹紧制动时瞬时大流量的需求,采用比例伺服阀和插装阀驱动制动器对工作台进行快速制动,其整体响应时间为63ms,模糊PID控制提高了系统的同步控制精度,同步误差最大为0.09mm,达到了试验台的控制要求,解决了垂直冲击试验台负载质量大且易产生二次冲击的问题。The hydraulic control system of the vertical impact test-bed is designed.The system model is established and the stability and fast rebound braking characteristics and synchronization characteristics of the closed-loop position control system are simulated and analyzed of the impact test-bed.The hydraulic system is composed of a combined power source of hydraulic pump and accumulator.The research results show that The system can meet the flow requirements during synchronous control and the instantaneous high flow requirements during rapid clamping and braking.The worktable is quickly braked using proportional servo valves and plug-in valve driven brakes.The overall response time is 63ms.The fuzzy PID control improves the synchronous control accuracy of the system.The maximum synchronization error is 0.09mm.These meets the control requirements of the test-bed.The problem of large load and easy secondary impact on the vertical impact test bench can be solved.
