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。
The European standard EN50318 is used to evaluate the accuracy of the simulation method for the dynamic interaction of the bow and net. Based on the finite element theory, a simulation method of bow-net interaction is established. By establishing the nonlinear three-mass pantograph and catenary model, the contact elements are set up to establish the pantograph / catenary coupling model, and the Newmark method is used to solve the problem. According to the procedure of EN50318, the accuracy of this method is verified. The simulations of different combinations of catenary types, tension combinations, span and pantograph types are consistent with the results of the Siemens simulation system and the CATMOS simulation system verified by the EN50318 standard. It proves that this simulation method Effectiveness.
