摘　　要：抗侧滚装置越来越多地在地铁车辆上应用,在设计时需要对其与构架和车体进行干涉分析。文中以扭臂安装在车体底部型式的抗侧滚装置为研究对象,分析了抗侧滚装置的运动轨迹,对拉压杆与构架以及转臂与车体安装座的干涉情况采用二维和三维两种方法进行了详细的分析和对比,并提出了对于弯曲型式的转臂只需要对其上侧棱边进行干涉分析就可验证部件间的间隙是否满足设计要求,对该类型抗侧滚装置的干涉分析提供了方法和思路。Anti-rolling torsion bar is more and more widely equipped in metro vehicles. It is essential to analyze the dynamic clearance between lever of anti-rolling torsion bar and installation seat of carbody in design. This paper analyzes the trajectory of lever through 2D as well as 3D modelling, and argues that the analysis of lever top edge is enough to verify whether the clearance can meet the design requirements. It provides an effective method for the clearance analysis of similar structure design in metro vehicles.
