摘　　要：针对机电液一体化系统联合仿真对硬件及操作人员要求过高的问题,提出基于同一仿真平台Matlab建立复杂系统虚拟样机的方法。以建立液压挖掘机虚拟样机多域仿真模型为例,采用Matlab软件SimMechanics工具箱、SimHydraulics工具箱和Simulink工具箱分别建立了液压挖掘机的机械系统、液压系统和控制系统仿真模型,并通过各模型间的接口技术,实现了机械、液压、控制子系统的有机集成。仿真结果证明:该方法可在样机设计阶段进行系统整体性能分析,能及时发现错误,降低开发成本,为复杂机电液一体化系统的多领域仿真分析提供了有效方法。A method of constructing virtual prototype for complex mechanical system based on the same platform of Matlab is proposed. It can overcome the difficulties of co-simulation of hydromechatronics system of hardware as well as high requirement of operating staff. Taking the construction of hydraulic excavator multi-domain virtual prototype as an example, the simulation model of mechanical system, hydraulic system and control system of excavator are established respectively. Matlab toolboxes of SimMechanics, SimHydraulics and Simulink are used in the simulation. Subsequently, the interface technique of various models is investigated. This work perfectly integrates hydraulic and mechanical systems with control system of excavator. The simulation results show that the method can analyze the overall performance of the system in the prototype design phase, find out the mistakes in time and reduce development costs. It also provides an effective method for the analysis of multi-domain simulation of complex electromechanical system.
