| 摘 要： | 建立地铁弹性扣件轨道的落轴冲击有限元模型,对目前地铁中采用的三种典型扣件:一般弹性扣件、粘结板式弹性扣件和轨道减振器扣件进行落轴冲击响应仿真分析,对比分析了减振性能,并重点分析扣件质量、刚度对减振性能的影响。分析结果表明:在建模时考虑部件质量、刚度能更好的反映钢轨扣件的实际减振性能,为弹性扣件的设计提供参考价值。

| Abstract: | Depending on the FEM model,the dynamic responses were simulated and calculated for different railway structures impacted by a falling wheel-set and the track's vibration isolation performances with different types of fasteners were compared with each other.Three typical types of fasteners were concerned:the common elastic rail fastener,the felting plate elastic rail fastener and the super-elastic fastener.The dynamic responses were analysed considering the influence of fastener components parameters (mass a... |
