    Abstract
  • Based on the nonlinear finite element theory(FEM), a finite element model of the pantograph-catenary dynamic system of Beijing-Tianjin intercity high-speed railway was established, in which nonlinear flexible catenary was modelled by using Euler-Bernoulli flexible beam and the pantograph was modelled by using hinge and nonlinear springs. The dynamic current-collecting performance of the system was simulated by using MARC software, and using whose post-processing function, the three dimensional dynamic performance of pantograph-catenary was shown. Computation result shows that the average pantograph-catenary contact pressure is 160.68 N and the dynamic uplift of contact position is between 28.5 mm and 87.0 mm. Compared with the simulation result provided by Siemens and the measure result, the model is correct and credible, the dynamic current-collecting performance is perfect.
