Modeling and Implementation of Hydraulic Motor with Digital Distribution and Speed Adjusting Mechanism

Abstract

Abstract: A new type of hydraulic motor with digital distributor on which ten high speed solenoid on/off valves are mounted was investigated. The operating principle and the structure characteristics are introduced. The mathematical model of this hydraulic motor is established and the simulation about speed adjusting and direction change characteristics is conducted. The simulation results show that the new digital distributor can not only realize the speed adjusting by varying the duty cycle of the control signal but also change the rotary direction of the new hydraulic motor by switching the distribution tables. Finally, the model machine of this new type of hydraulic motor was developed and experiments were carried out to validate the simulation results. The experimental results show that the model of the new hydraulic motor is correct and effective.

Key words: digital distribution and speed adjusting, hydraulic motor, modeling, high speed solenoid on/off valve
