阀控缸液压系统变负载工况速度稳定性研究

Speed Stability of Valve Control Cylinder Hydraulic System Under Variable Load Conditions

围绕某发射装置,在大负载变惯量、大发射冲击以及快速响应性等条件下,适应速度控制要求,解决了阀控缸液压系统抖动问题。提出了阀控缸液压系统在大推力小力臂条件下液压锁的一种模式,即基于双反向型平衡阀组合的液压锁定方式和参数系统。通过原理分析、仿真分析、改进设计和试验验证,说明这种模式是发射装置应用中非常有效的一种方式,适合受力力臂小,负载变化大且出现正反两个方向的场合。

Around a launch device.It adapts to the speed control requirements under the conditions of large load inertia,large launch impact and rapid response of the rocket.It solves problem of the vibration of the valve-controlled hydraulic system.A mode of hydraulic locking of the valve-controlled hydraulic system under the condition of large thrust and small force arm is proposed,which is based on the hydraulic locking mode and parameter system of the reverse-type balance valve.Through the principle analysis,simulation analysis,improved design and test verification,this model is a very effective way in the rocket launcher application.It is suitable for the small force arm,large load change and positive and negative in both directions.
