直线电机地铁系统是一种新型的城市轨道交通模式,它采用直线感应电机牵引,轮轨支撑导向。根据系统特点,建立直线电机地铁系统垂向车辆-轨道耦合模型。在此基础上编制计算机仿真程序,分析确定性不平顺对车辆和轨道动力响应特性及直线电机气隙变化的影响规律。
Linear motor metro system is a new type of urban rail transit mode, which uses linear induction motor traction, wheel and rail support-oriented. According to the characteristics of the system, a vertical vehicle-track coupled model of linear motor metro system is established. Based on this, a computer simulation program is compiled to analyze the influence of deterministic irregularities on the dynamic response characteristics of vehicles and orbits and the variation of air-gap of linear motor.
