我国高速列车均采用电力牵引，作为列车能量来源的受电弓/接触网系统随着列车速度的提升也面临着新的挑战。如何保证列车不间断地、可靠地从接触网上取流是弓网关系的核心问题。本文在国内外已有受电弓/接触网动力学研究的基础上开展相关研究，主要完成了以下几个方面的研究内容：
首先针对俄罗斯莫-喀高铁所选用接触网进行了基于ANSYS的有限元建模，包括50m，55m，60m，65m和70m等五种不同跨距接触网模型。对接触网进行模态分析，对其动态特征进行相应的研究。
其次，提供获取受电弓归算质量模型参数的方法。在此基础上建立基于ANSYS平台的归算质量、基于SIMPACK平台的多刚体和刚柔耦合的受电弓/接触网耦合模型。以Faiveley公司的CX型受电弓为例进行模态分析。
然后，根据已经建好的不同跨距接触网模型，对单弓运行和双弓运行进行研究。单弓运行时，分析不同跨距下弓网动力学性能并找出适用性；双弓运行时，考虑双弓间距影响因素，研究各跨距接触网下弓间距的适用情况。
之后，以60m跨距接触网和DSA380型受电弓为例，分别研究接触网吊弦根数、张力和受电弓弓头质量、弓头悬挂等参数对弓网动力学性能的影响。
最后，在建立车-弓-网整体模型的基础上，考虑不同线路条件对弓网动力学性能的影响，包括线路曲率半径，超高等线路条件。

China's high-speed trains are all using electric traction, as the energy source of trains, the system of pantograph / catenary is facing new challenges with increasing train speed. How to ensure the uninterrupted, reliable access from the contact network is the core of the relationship between pantograph and the catenary. In this paper, the research on the dynamics of pantograph / catenary has been carried out based on the studies from both China  and abroad, and has completed several research points:
Firstly, the finite catenary models which are being used by Mohao high-speed railway in Russia have been establishedbased on ANSYS software, including five different spanlengthes 50m, 55m, 60m, 65m and 70m. The modal analysis of the catenary is carried out, and theirs dynamic acteristics have been analyzed.
Secondly, provided the method of how to get the equal parameters of pantograph. Then establish the multi-body model based on SIMPACK software and rigid-flexible coupling model based on ANSYS software. As an example, carrying out model analysis of Faweilei's CX pantograph.
Thirdly, study the dynamic of singal and double pantographs based on the exist catenary models. While there is only one pantograph,give out the dynamic performances. While there are two pantographes, consider the distance between the two pantographs. Then research the influence and give the applicability of the distance.
Fourthly, use the 60m spanlength catenry and DSA380 pantograph as an example, do reserches on the influence of parameters, which include dropper amount，catenary tensile force，mass of pantograph bow，stiffness of pantograph bow.
Finally， establish vehicle-pantograph-catenary model based on SIMPACK, study the dynamic performances that consider different line conditions ,which include curvature radiu, suerelevation.
