[[abstract]]擺式列車是一種有別於傳統軌道車輛的設計，大多用於地狹人稠的地區，或是都會型的城市。利 用機電系統控制傾擺機構，使得列車在轉彎時不需要降低行駛速度，可縮減旅程時間。 本研究計畫預定探討擺式列車車輛系統於行駛中的動態行為，考慮具滾動導軌式傾擺機構之車輛 系統、車輪/軌道間非線性的潛滑力與潛滑力矩以及外在風力的作用，探討擺式列車系統在曲線軌道運 動之穩定性分析與動態行為分析。預計逐步完成以下各項研究： (A)考慮車輪/軌道間非線性的潛滑力與潛滑力矩，探討不同傾擺角度下，擺式列車之車輛系統在曲 線軌道運動的動態穩定性分析。 (B)考慮車輪/軌道間非線性的潛滑力與潛滑力矩以及外在風力，探討不同風速的作用下，擺式列車 之車輛系統在曲線軌道運動的動態行為分析。 (C)考慮車輪/軌道間非線性的潛滑力與潛滑力矩以及外在風力，探討不同的風力作用角度下，擺式 列車之車輛系統在曲線軌道運動的動態行為以及轉彎性能分析。[[abstract]]The tilting train is different from traditional railway vehicles. It is usually used for the transportation in the city. The electro-mechanical system is used to control the tilting mechanism. Therefore, the speed of tilting train has not to decrease on curved negotiation. The trip time can also be reduced if the speed of tilting train increases on curved tracks. In this project, we will discuss the dynamic behavior of tilting train vehicle system. Considering the tilting mechanism of roll-guide type, the nonlinear creep forces and moments, and wind loads, the dynamic stability and dynamic responses analysis of tilting train moving on curved tracks are investigated. We will finish this research with the following steps: (A) The dynamic stability analysis of tilting train vehicle considering the nonlinear creep forces and moments with the various tilting angles. (B) The dynamic response analysis of tilting train vehicle considering the nonlinear creep forces and moments, and wind loads with the various wind speeds. (C) The dynamic response analysis of tilting train vehicle considering the nonlinear creep forces and moments, and wind loads with the various acting angles of wind loads.[[note]]NSC99-2221-E327-01
