在对具有轨道板结构的无碴轨道分析基础上,建立了预制式轨道板结构的力学模型,即刚体模型。通过对分布式轨道板结构不同的纵向布置对车辆系统的振动响应影响分析,得到了高架桥无碴轨道中预制式轨道板的合理布置方式。
Based on the analysis of the ballastless track with orbital plate structure, the mechanical model of the prefabricated orbital plate structure is established, that is, the rigid body model. Through the analysis of the influence of longitudinal arrangement of distributed track slab on the vibration response of vehicle system, the reasonable layout of prefabricated track slab in ballastless track of viaduct was obtained.
