摘　　要：通过仿真软件SIMPACK建立装用自导向径向转向架的摆式客车模型,介绍了模型建立的方法,与常规转向架对比分析300 m小半径曲线通过的动力学性能。分析表明,自导向转向架在轮对冲角、轮轨横向力、磨耗指数和脱轨系数上,无论是最大值还是变化幅度都比常规转向架要低很多,自导向转向架运用于摆式客车小半径曲线通过依然具有良好的效果。This paper estabhshed a tilting train model equipped with self- steering radial bogies via simulation software SIMPACK and introduced how to build it, then compared and analyzed its dynamics performances along small curve - passing radius of 300 m. The analytic results shaved that attack angle of wheelsets, wear index, wheel/rail lateral force and derail coefficient of self- steering radial bogies were much lower than those of normal bogies not only on maximal value but also on variation amplitude. Self - steering bogies with application to tilting trains still had good efforts on small curve - passing.
