Dynamic Performances of Pantograph-Catenary System with Double Pantographs

  • Received Date: 03 Sep 2008
  • Finite element models for the catenary and the double pantographs were derived.The latter was simplified as a multi-lumped-mass system.The two models was coupled by contact elements to form a pantograph-catenary system model,and its dynamic equilibrium equations were presented.The parameters in the pantograph-catenary system model were calculated with the time integration method.The results show that the rear pantograph has a little influence on the current collection performance of the front pantograph,and the front pantograph has an obvious impact on the rear pantograph.The space between the two pantographs has not obvious effect on uplift and contact force of the front pantograph,and has obvious impact on those of the rear pantograph.The current collection performance of the rear pantograph is the worst when the space between the two pantographs is 90 or 150 m,and the preferable space is 200 or 210 m.
