摘　　要：挖掘机整机包括液压、机械和控制系统,运用MATLAB软件建立各个系统的仿真模型,并将其组装成整机仿真模型进行仿真,最终得到工作装置的运动轨迹。根据仿真结果对各个系统进行分析,可以用于研究液压和机械系统参数改变对系统性能的影响。液压和机械系统分别由SimHydraulics和第二代SimMechanics工具箱建立,根据实际液压元件的特性和工作装置的尺寸参数设置仿真模型的参数,以得到准确的仿真结果。此虚拟仿真可实现机、电、液一体化仿真,可为挖掘机各系统的优化设计提供参考依据,也为研究挖掘机各系统提供了一种新思路。The whole set of excavator was composed of hydraulic,mechanic and control systems. Simulation model of each sys-tem was built through using MATLAB software,and then the whole set of excavator model was gotten through connecting different sys-tems and simulated. Finally the motion trajectory was obtained for the manipulators. The influences on system performance by changing parameters of hydraulic and mechanic systems could be studied through analyzing each system according to the simulation result. The hydraulic and mechanic systems were built by SimHydraulics and Second Generation SimMechanics tool-box respectively,and accurate simulation results were obtained by setting the parameters of simulation model based on the actual characteristics of hydraulic elements and measurements of manipulators. This virtual simulation can implement an integrative technique of mechanics electronics and hydrau-lics simulation,which can provide references for optimizing design of different systems of excavator,at the same time,provide a new method to studying each system of the excavator.
