摘　　要：针对电子整机中高速互联背板传输载体运用有限元法分析电磁兼容计算周期过长问题,采用有限元仿真分析软件AnsoftHfss、均匀试验设计和径向基神经网络(RBFNN)构建高速互联背板传输载体电磁兼容分析的代理模型,并对构建流程进行详细介绍。通过算例分析,证明该方法在保证一定精度前提下较好降低了电子整机中高速互联背板传输载体电磁兼容学科的计算周期。Aiming at long calculation time when computing EMC of High-Speed Intarconnection Backplane with FEM in Electronic Equipment,a method for constructing surrogate model for EMC of High-Speed lnterconnection Backplane was put forward by means of Ansoft HFSS, uniform experimental design and radial basis functionneurai network（RBFNN）, and its constructing process was analyzed in details. Trough the sample analysis, RBF neural network Surrogate Model was proven to short the time of computing EMC of High-Speed Intarconnection Backplane effectively.
