摘　　要：现代产品的开发需要多领域建模仿真工具支持。分析了AMESim/Modelica模块在多领域系统级建模仿真方面的优势。以汽车电动助力转向系统(EPS)为例,采用图形化物理建模方式在AMESim中建立了系统模型,并用多领域统一仿真建模语言Modelica编写的模型替换了部分模型,分析了转向过程中系统参数对转向性能的影响。仿真结果表明:AMESim/Modelica模块建立的电动助力转向系统模型的可读性好,同时Modelica建立的子模型重用性好,该方法是一种直观化、易操作的设计方法。The development of modern products needs the support of multi-domain modeling and simulation tools.The superiority of AMESim/Modelica module in multi-domain system-level modeling and simulation was analyzed.By example of the electric power steering system（EPS）,the system model was established in AMESim by bond graphic physics modeling,and some models were replaced by the models edited by Modelica the multi-domain simulation modeling,and the influence of the system parameters on the steering performance in steering process was analyzed.The simulation results show that the EPS system model built by AMESim/Modelica module is easily readable,and the sub-model edited by Modelica is easily reused,and it is a visual and easily operating system design method.
