Modeling and Simulation of Micro Hydraulic Transducer Based on Component Library

Abstract

For MHT is an integrated system for different domains, namely fluids, structures, piezoelectrics and circuitry, a component library consisting of inlets, outlets, chambers and piezoelectric blocks is developed with Modelica. The governing equations of inlet and outlet channels, chamber and piezoelectric block are proposed and parameter models are created based on object-oriented method with Modelica. Then the model of MHT is established by connecting different components’ pins of equivalent type. Simulation results on Dymola show accordance with that on Simulink, which indicates that this method can achieve high efficiency and precision.
