摘　　要：基于空气弹簧的气动力学模型与车辆的多体动力学模型,对2点支撑模式与4点支撑模式下车辆的动力学性能进行了对比研究。此外,分析了2种改进的支撑模式:增加抗侧滚扭杆的4点支撑模式与差压阀可调的前3点支撑模式。研究结果表明,采用2点支撑模式与4点支撑模式的动车组具有较相似的动力学特性;增加抗侧滚扭杆的4点支撑模式能够保证故障状态下车辆的运行安全性;差压阀可调的前3点支撑模式能够在一定程度上提高车辆的曲线通过性。Based on the pneumatic model of air spring and the dynamics MBS model of EMUs,the dynamics behaviors of EMUs in the 2-point configuration and 4-point configuration were studied contrastively.What＇s more,two improved suspension morphologies were analyzed,including the 4-point configuration with anti-rolling bar and the front 3-point configuration with the controlled differential pressure valve.The results of the research indicated that：the EMUs with 2-point and 4-point configurations possed the similar dynamics behaviors;the 4-point configuration with anti-rolling bar could ensure the running safety of EMUs in the fault cases; the front 3-point configuration with the controlled differential pressure valve could improve the EMU＇s ability of passing curve in certain extent.
