摘要
建立了某高速列车动力学模型及该列车一系悬挂阻尼三维结构原理图,基于该结构研究了列车一系悬挂阻尼常见的失效形式,并仿真分析了一系悬挂阻尼发生故障对车辆运行品质的影响。研究结果表明:一系悬挂阻尼常见故障主要由骨架密封磨损严重、O型圈老化严重、油液乳化等引起;当每辆车1个或每辆车2个一系悬挂阻尼发生故障,车辆横向及垂向平稳性受影响较小,其指标恶化率小于5%,但对舒适性有一定影响,舒适性指标恶化率最高可达15%;当车辆一系悬挂阻尼全部发生故障,其运行品质存在显著恶化,而舒适性恶化最为严重,其指标恶化率达186%。
The dynamic model of a high-speed train and the three-dimensional structural schematic diagram of the primary suspension damping of the train are established. Based on the structure, the common failure forms of the primary suspension damping of the train are studied, and the influence of the primary suspension damping failure on the running quality of the vehicle is simulated and analyzed.The results show that the common faults of primary suspension damping are mainly caused by the serious wear of the skeleton seal, the serious aging of the O-ring and the emulsification of oil. Vehicle lateral and vertical stability is less affected as one damper or two dampers(one for each bogie) are failure. The index deterioration rate is less than 5%. Comfort has a certain impact, the index deterioration rate is up to 15%. Running quality deteriorates significantly as primary suspension dampings are all failure. Comfort deterioration is the most serious and the deterioration rate of the index reaches 186%.
