摘　　要：针对在EASY5设计的液压系统仿真模型基础上实现半物理仿真系统设计中存在的相关问题,采用EASY5和MATLAB/Simulink的联合仿真模型,在MATLAB/Simulink环境中调用Win-dows API的多媒体定时器的方式实现实时仿真控制,以克服EASY5不能实时仿真的不足;采用TCP/IP网络通信实现仿真机和测控机的数据交互;用Visual Basic设计仿真机的人机界面,实现对半物理仿真试验的数据设置和仿真启动。从试验图可以看出半物理仿真试验效果良好。Co-simulation of EASY5 and MATLAB/Simuliink was introduced to overcom prob- lems on hardware in the loop simulation system design issues based on hydraulic system simulation model with EASY5, and the Windows API was called for multimedia timer real--time control to o- vercome the real--time problem of EASY5 in the MATLAB/Simulink simulation. TCP/IP network communication was used for data exchange between simulator and control machine. Man--machine interface of simulator was designed with visual basic, to achieve experimental initialization the hard- ware in the loop simulation system and start the simulation. It can be seen from the test results that the hardware in the loop simulation system works well.
