In particular, the stability and ride quality of the vehicles will be discussed in detail based on full-scale experimentally measured data. In the analysis, many nonlinear quantities existing in the railway vehicle system such as conicity, suspension system, track irregularity and the contact force between rail and wheel will be considered. The dynamic stability and ride quality analyses of railway vehicle moving on straight as well as curved tracks will be performed and verified by the experimental results. The dynamic response of railway vehicles subjected to earthquake loading will also be investigated in order to understand the earthquake effect on the stability and safety of vehicles. The effect of earthquake ground acceleration on the dynamic behavior of vehicle derailment factor and track shift force will be revealed accordingly.軌道車輛穩定度乘車品質舒適度車輪圓錐度軌道不平整度接觸力脫軌移軌力Railway VehicleStabilityRide QualityConicityTrack IrregularityContact ForceDerailmentTrack Shift Force軌道車輛之動態分析及實車測試驗證(2/2)
