In order to compare the influence of different data processing method on the dynamic performance of a locomotive,we use the multi-rigid-body dynamics software SIMPACK to establish the dynamic model of some highpower AC drive electric locomotive,process the simulation results of the locomotive that dynamically negotiates the300 m radius curve with different methods and compare them with the test results. The test results show that: 1) the data processing method has a great influence on the dynamic performanc...
