The Parameters Dynamic Study Of Pantograph/Catenary

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 characteristics 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.
