摘　　要：以模块化建模方法为指导,提出了液压系统的热力学模块化建模方法。将液压元件工作机理分为容积型和阻尼型,建立容积型模块和阻尼型模块模型,由容积型模块和阻尼型模块单独或组合建立液压元件的模块化模型。采用Dymola对所建立的各元件模型进行仿真实现,建立了温度仿真模块库-ThermalHydraulic,可以实现面向液压原理图的可视化温度仿真。对模块库进行测试,验证了建模和仿真实现的可行性。According to the modular modeling method,a thermal-hydraulic modular modeling method of hydraulic system was presented. Basic operating principles of all hydraulic components were divided into two types：volume and resistance. Volume model and resistance model were developed to represent the volume and resistance characteristic of hydraulic component. Component＇s modular model was established by signal or both of volume model and resistance model. Then,the hydraulic system temperature simulation modular library-Thermal Hydraulic was established by Dymola software,and the library could establish system model conveniently by visual modeling style based on hydraulic principle figure. At the last,the system test was made to evaluate the feasibility of modeling and simulation.
