Mathematical modeling of dynamic processes in a hydraulic drive with a discrete regulator of liquid flow

Abstract


The paper presents a mathematical model of a hydraulic drive with a discrete liquid flow regulator in the form of a switched inertial device that has a damper of working medium oscillations at the output. A hydraulic actuator loaded with mass was used as a final control element. Transition processes occurring when the regulator is activated are calculated by modeling the dynamic processes with the help of the Simulink software package. The research shows the impact of the valve operating frequency and pulse ratio on the dynamics and efficiency of the hydraulic drive. It could be concluded that the use of a hydraulic attenuator results in decreasing the level of pressure ripples at the inertial tube input.
