Abstract:

基于不明原因列车脱轨机理与运动系统平衡状态稳定性分析的能量增量准则,提出了列车-轨道(桥梁)时变系统横向振动稳定性与失稳临界车速分析方法,确定了系统横向振动最大输入能量及其增量,计算了系统横向振动极限抗力做功及其增量,建立了系统横向振动稳定性评判准则,计算了系统横向振动失稳临界车速。通过算例,计算了高速列车-无砟轨道时变系统横向振动稳定性及控制高速列车安全运行的指标。计算结果表明高速列车-无砟轨道时变系统横向振动的失稳临界车速为647.3km.h-1,容许极限车速为517.84km.h-1,抗脱轨安全度为1.85,因此,高速列车以350km.h-1的车速在无砟轨道上运行是安全的。
