Research on Speed Control in Starting and Stopping Processes of Hydraulic Cylinder with HSV

Abstract

Abstract:

A hydraulic loop that HSV connected between rod cavity and no-stem cavity of hydraulic cylinder was designed to study the speed control problem in the starting and stopping processes of hydraulic cylinder.The starting and stopping speed control problem of hydraulic cylinder was studied by simulation and experiments.Research results show that HSV can reduce the maximum starting acceleration and the final velocity effectively,and can realize the speed control in the starting and stopping processes of hydraulic cylinder.

Key words: hydraulic system, high speed on-off valve(HSV), speed control, simulation

摘要：

为了研究液压缸起动和到位过程中的速度控制问题,设计了高速开关阀与液压缸并联连接的油路,即将高速开关阀连接于液压缸有杆腔与无杆腔之间。分别针对液压缸起动和到位两个过程的速度控制问题,开展了仿真与实验研究。研究结果表明,高速开关阀能有效降低液压缸起动时的活塞最大加速度和到位时的活塞末速度,实现起动过程和到位过程中的速度控制。
