摘　　要：针对国内某型160 km/h高速机车,归纳出4种典型的抗蛇行减振器布置方式,并通过SIMPACK建立机车动力学模型。以提高机车横向平稳性和蛇行稳定性为目标,采用基于全因子DOE方法对抗蛇行减振器阻尼、关节刚度和横向安装角进行优化,并利用Pearson相关性系数分析法研究抗蛇行减振器参数对机车横向动力学性能影响规律。研究结果表明:布置方式对机车横向动力学性能具有显著影响,当采用开口向外布置方式时,机车可实现较优的横向平稳性且可以通过调整横向安装角来消除前后司机室横向平稳性差异。此外,减小抗蛇行减振器阻尼和关节刚度有利于改善机车横向平稳性和蛇行稳定性,与布置方式无关;但横向安装角对横向动力学性能的影响受到布置方式的影响。For a certain type of domestic high-speed locomotive with a top speed of 160 km/h,four types of yaw damper layout schemes were summarized,and the corresponding dynamics models were established by SIMPACK software.Then,in order to improve the lateral ride comfort and hunting stability of the locomotive,the method of full factor DOE was utilized to optimize the damping,series stiffness and lateral installation angle of yaw dampers simultaneously,and the influence law of yaw damper parameters on the locomotive lateral dynamics performance was researched through the analysis method of Pearson correlation coefficient.The results show that the layout scheme of yaw dampers has a significant impact on the locomotive lateral dynamics performance.Specifically,when the layout scheme of opening outward is adopted,the locomotive can attain a better lateral ride comfort,and the difference in lateral ride comfort between the front and rear cabs can be eliminated by adjusting the lateral installation angle.In addition,reducing the damping and series stiffness of yaw dampers is conducive to improving the locomotive lateral ride comfort and hunting stability,which is regardless of the layout scheme of yaw dampers,but the influence of the lateral installation angle on lateral dynamics performance is affected by the yaw damper's layout scheme.
