摘要
针对轨道交通列车车门辅助锁工作过程中存在运动不平稳、冲击力大的问题,通过RecurDyn软件的AutoDesign功能对辅助锁的结构尺寸进行了优化,以滚轮直径、滚轮的旋转半径及摆臂凸轮的接触轮廓作为设计变量,以锁舌旋转角速度、锁舌旋转角加速度及锁舌转角作为约束条件,对仿真模型进行优化。仿真结果与试验结果均表明:优化后的凸轮与锁舌的接触过程更加平滑,承载能力得到了加强。
In view of the problems of unsteady movement and large impact force in the working process of rail transit train door auxiliary lock,the structural dimension of the auxiliary lock was optimized by the AutoDesign function of RecurDyn.The design variables are the diameter of the roller,the rotation radius of the roller and the contact profile of the swing arm cam.Taking the rotation speed of the lock tongue,the acceleration of rotation angle of the lock tongue and the rotation angle of the lock tongue as the constraint conditions,the simulation model is optimized.Both simulation and experiment results show that the contact process between the optimized cam and the locking tongue was smoother,and the bearing capacity has been strengthened.
