摘　　要：为减少山地齿轨轨道交通中传统转辙机拉杆槽结构道岔的转辙机数量、优化结构布局、减少占地面积,文中设计了一款新型道岔转换系统,其采用连杆结构使可动齿轨成对运动。使用ADAMS软件完成系统的动力学和运动学仿真,得到关键零件的运动参数和运动规律;使用Ansys完成工作时的受力仿真分析,得到关键零件的强度和应力。仿真结果表明:使用新型齿轨道岔转换系统后,安装一台转辙机就能同时驱动两组可动齿轨,实现齿轨道岔转向的工作任务。整套系统结构不存在死点,工作时装置运行平稳,强度刚度符合要求。In order to reduce the number of switch machines,optimize the structural layout and reduce the occupied area of traditional switch machines with tie bar slot structure in mountain rail transit,a new turnout switching system is proposed in this paper,which uses a connecting rod structure to drive the movable rack to move in pairs.The dynamics and kinematics of the system are simulated using ADAMS software,and the motion parameters and laws of key parts are obtained.The stress was simulated and analyzed through Ansys,and the strength and stress of key parts were obtained.The simulation results show that two sets of movable racks can be driven at the same time with only one switch machine,so as to realize the rack turnout steering.There is no dead point in the whole system structure,the device runs smoothly,and the strength and stiffness meet relevant requirements.
