朔黄铁路2万t重载组合列车纵向车钩力分析及应用研究

Analysis and Application Research on Longitudinal Coupler Force of 20,000 t Heavy-haul Combined Train on Shuozhou-Huanghua Railway

结合朔黄铁路2万t重载组合列车动力学试验数据,研究2万t重载组合列车在朔黄线不同线路区段的列车纵向车钩力、纵向加速度等动力学指标分布规律及其安全性能,分析其影响因素,提出降低列车运行安全风险的技术对策。

With the dynamic test data of 20,000 t heavy-haul combined train on Shuozhou-Huanghua Rail⁃way,this paper researches the distribution rule and safety performance of dynamic indexes such as longitudi⁃nal coupler force and longitudinal acceleration of 20,000 t heavy-haul combined train in different sections of Shuozhou-Huanghua Railway,analyzes the influencing factors,and puts forward technical countermeasures to reduce the safety risk of train operation.
