摘要
为研究GH-1轨道交通新型减振扣件对列车稳定性的影响,进行轨道行车稳定性试验,测试列车通过不同轨道减振扣件区时转向架及车厢的横向和垂向振动加速度,与现行国际规范及国家标准规定的列车运行安全性和平稳性指标进行对比,并比较分析列车在不同扣件区的振动加速度响应。结果表明,列车通过GH-1新型轨道减振扣件区时,列车安全性和平稳性能够满足标准规定的限值,且车体的横向和垂向振动响应以及转向架的横向振动响应相对于列车通过国内常用的DT系列某型号扣件区时更小,列车稳定性更好。该结果对GH-1轨道交通新型减振扣件的使用安全具有参考价值。
To study the influence of GH-1 rail vibration damping fasteners on train operation stability,the train stability tests are carried out.The lateral and vertical vibration accelerations of the bogie and carriage are measured when the train passes the track area with different damping fasteners.The safety and stability indexes of the train in operation are analyzed and compared with those given in international standard and domestic standard.It is concluded that the train safety and stability can meet the standards when passing through the track area with GH-1 rail vibration damping fasteners,and the vibration accelerations of the bogie and carriage are smaller than that with DT fasteners.Thus,the train operation stability is good.The conclusion is meaningful for the design and safety application of the new damping fasteners.
