Influence of Catenary Stitch Wire Parameters on Dynamic Performance Between Pantograph and Catenary

  • 摘要: 为确定不同速度等级接触网弹性吊索参数的优选值,利用有限单元法,建立了中国高速铁路250、350 km/h两种速度等级的受电弓、接触网和弓网接触的动力学仿真模型,得到受电弓与接触网的动态性能指标,比较双弓作用下不同接触网弹性吊索截面积、张力和长度的弓网接触力数字特征和接触网定位点最大抬升. 研究结果表明:适应250 km/h的O2-1型接触网弹性吊索宜选用线型为JTMH 35 mm2、张力范围为(2.80 ± 0.10) kN,长度为14 m或18 m;适应350 km/h的京沪高速铁路接触网弹性吊索宜选用线型为JTMH 35 mm2、张力范围为(3.50 ± 0.10) kN,长度为18 m;弹性吊索参数变化对前弓的接触力影响较小,对后弓的接触力影响显著;250 km/h和350 km/h下弹性吊索长度22 m的定位点最大抬升分别是长度18 m的111%和117%,弹性吊索长度的变化对定位点最大抬升影响显著.
