摘　　要：在铁道车辆曲线通过时，推导出轮对所在轨道坐标系相对轨道动坐标系的几何约束关系，并通过两个动态曲线通过算例对理论推导的结果作了验证，为开发通用车辆动力学仿真软件提供了轨道约束单元。In this paper, the geometry constrain of normal track coordinate system on curve is derived in detail. Treated as active constrain of multibody system , it is verified by simulating the dynamics of a wheelset and an artificial bogie on dynamic curving negotiation. It has been implemented into the multibody system dynamics simulation software ROSDY.
