摘要：
For resolving errors between a simulation analysis and the test results of a large system, a multi-body simulation model of a railway wagon with 26 degrees of freedom was created using test data from a real test rig on a railway track and by incorporating the wagon body's subsystems into the simulation object in order to realise a simulation calculation of the dynamic response of the railway wagon. The results show that the maximum RMS (root mean square) error between the simulation and the test of the wagon body bolster's vertical and lateral vibration acceleration is 9%. Furthermore, the RMS error between the simulation and test of the wagon body bolster's vertical and lateral vibration acceleration is less than 8.57% in the 1.5-15.0 Hz frequency range. Finally, the response signal waveforms of the dynamic stress of the simulation and that of the wagon body's key welds are almost identical. The comparison and validation of the simulation and test results show that the simulation results substantially reproduce the dynamic response conditions of the railway wagon running along a railway track. © 2019, Editorial Department of Journal of Southwest Jiaotong University.
