防滚和解耦是中低速磁悬浮列车悬浮架的重要功能。本文基于虚拟样机技术，比较分析弹性解耦和几何解耦方式对悬浮架防滚和解耦功能的影响，提出吊杆型防滚解耦机构的防滚和解耦功能是相互制约的，几何解耦方式表现出非对称性，左右模块相对轨道的滚动角不相等，对磁浮列车的安全运行不利。考虑到悬浮控制和轨道不平顺，吊杆型防滚解耦机构应采用半弹性解耦的方式。

Anti-rolling and decoupling are the two important functions of low-speed maglev bogies.Utilizing the virtual prototyping technology,the different characteristics of the elastic-decoupling mode and the geometric-decoupling mode of the boom-type anti-rolling and decoupling mechanism (ADM)were investigated.Restraints between anti-rolling and decoupling were presented.The geometry-decoupling mechanism demonstrated asym-metric features,i.e.,the rolling angles between the left and right suspension modules and tracks that met were different,which put a maglev train at a disadvantage in view of running safety.Since track irregularities and gap fluctuations of levitation were unavoidable,the semi-elastic decoupling mode was recommended for the boom-type ADM.
