Design of Bypass-Throttle Hydraulic Cylinder Speed Control System Base on High-Speed On-Off Valve

Abstract:

Application of high-speed on-off valve in the hydraulic speed control system was researched in this paper. The bypass-throttle circuit application of high speed on-off valve is proposed to control the speed of hydraulic cylinder. The duty cycle of pulse control signal was changed according to the displacement of hydraulic cylinder to control the speed and weak the impact. The speed and accelerated speed curves of hydraulic cylinder were achieved by the means of simulation with Simulink and experiment with FESTO is obtained, and research result shows that the applied scheme can effectively control the speed of hydraulic cylinder effectively.
