摘要
以广州直线电机轨道交通系统板式轨道结构为例, 结合有限元理论以及直线电机的特点,建立了直线电机运载系统下的垂向耦合动力模型(包括车辆系统模型、轮轨关系模型、钢轨模型、板式轨道模型等)及其振动微分方程,并通过动力仿真试验,分析该系统的动力特性以及验证该系统的耦合动力模型。
Taking the structure of concrete slab track of linear induction motor(LIM) in Guangzhou as an example, through combination of finite element theory and the characteristic of LIM, the vertical dynamic coupling model of LIM in vehicle concrete slab track and the dynamic differential equation are set up. This paper analyses the dynamics characteristics of this system and tests the coupling model of this system through dynamics simulation.
