摘　　要：欧洲标准EN50318用于对弓网动态相互作用的仿真方法的准确性做出评价验证。基于有限单元理论建立了一种弓网相互作用的仿真方法。通过建立非线性三质量块受电弓模型和接触网模型,设置接触单元,建立受电弓/接触网耦合模型,并采用Newmark方法求解。依照EN50318的流程,对该方法的准确性进行验证。对多种接触网类型、拉力组合、跨距、受电弓类型等不同参数组合的仿真,该方法仿真结果与通过EN50318标准验证的Siemens仿真系统和CATMOS仿真系统的结果一致,证明了该仿真方法的有效性。EN50318 is applied in the validation of simulation of the dynamic interaction between pantograph and overhead contact line.Based on the finite element theory,this paper established a simulation of the pantograph/catenary interaction by establishing non-linear three-mass pantograph model and overhead contact line model.Contact elements were set to establish a coupling model of pantograph/catenary,and then calculated with Newmark method.The test of this model was done according to the procedures of EN50318.In simulating parameters of multiple contact lines,tension combination,span and different pantographs,the result of this model was proved valid in accordance with that of Siemens and CATMOS simulation systems certified by EN50318.
