摘　　要：介绍了某出口宽轨机车运输转向架的技术特点,采用多体动力学软件SIMPACK建立运输车的动力学模型,着重分析抗蛇形减振器阻尼和一系悬挂参数的变化对运输车稳定性、直线和曲线通过性能的影响。通过各参数的优化分析,结果表明运输转向架去除抗蛇形减振器对整车性能更有利,运输转向架一系悬挂装置完全采用SS8机车的是可行的,且满足运输车过轨安全性要求。Technic characteristic of the bogie for one exported broad gauge locomotive was introduced. Dynamic model of the locomotive transporter was established based on SIMPACK software, laying stress on analyzing how the yaw damper and parameter variation of primary suspension would affect the stability, straight and curve negotiation of the transporter. Through the optimizing analysis of the parameters, it was found that getting rid of the yaw damper led to better performance, and it was possible to adopt the primary suspension , of SSs locomotive as that of transporter bogie, with safety request fulfilled for transporter passing different railways.
