The pantograph on HEMU400 perform the simulation of following characteristics for pantograph’s performance prediction and confirming the EN50119"s requirement. To meet the performance requirements for the input data are proposed. Simulation result of the performance requirements are satisfied from proposed input data. The new model was developed by proposed data base on the simulation result. A new developed model data used in following characteristics meet to be sure about what the test was done to count the equivalence of mass. Depending on the results of test to performance prediction, and propose research directions.
