摘　　要：为突破复杂车体结构的电磁兼容(EMC)建模难题,提出了基于多软件的整车联合建模技术。利用有限元软件HyperMesh对复杂车体各关键部分的CATIA模型进行简化和网格剖分,开发Matlab程序提取剖分后的节点坐标数据,并在Matlab中编写形成网格模型的程序,重构成FEKO等电磁仿真软件可以处理的整车EMC模型。最后,建立了某型汽车整车级天线的电磁辐射发射模型,通过比较辐射场强的仿真和试验结果验证了方法的有效性。To overcome the difficulty for the electromagnetie compatibility （EMC） modeli,lg technology of the complex vehicle structures, this article proposed a multi-software vehicle level co-simulation technology. With the finite element soft- ware HyperMesh to simplify and mesh the complex CATIA model of a vehicle, develope Matlab program for extracting the grid data, and edit program in Matlab to build grid model, then import the vehicle grid to electromagnetic simulation software FE- KO to ohtain the desire accuracy vehicle level EMC model. Finally, the vehicle level antenna electromagnetic radiated emis- sion model of a certain type automobile is established , the radiated electric field strength modeling and simulation results verify the effectiveness of the method.
