摘　　要：针对EMS型中低速磁浮列车的模块结构决定系统存在垂向、侧向和滚动三自由度、滚动自由度自身不稳定,其稳定性由控制器与防滚结构共同保证的特点,建立了磁浮列车悬浮模块垂向和滚动的两自由度模型,利用劳斯判据判定特征多项式解的分布特性,从而得出了防滚装置参数设定的基本准则,并采用虚拟样机技术验证了该结论的正确性。该方案所获取的防滚弹簧参数下限的结论,为系统调试提供了参考,对磁悬浮列车技术的逐步成熟有实际意义。To the module stmcture of EMS low-middle speed tangler train possessing three degrees in vertical translation, horizontal translation and wiling, the wiling is unstable itself and its stability is guaranteed by controller and beam equipment against rolling. The mnglev model with two degrees in vertical translation and rolling is set up. The system stability is discussed according to Routh criterign. The basic acquirement for parameters of beam equipment against rolling is introduced, and the virtual prototyping technology to validate the conclusion. The result shows that the scheme guarantees limit stiffness of the spring against rolling, provides the reference for system experiment, and is used for the development of Maglev train technology.
