摘要
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。
A dynamic model for the prefabricated floating slabs is presented on the basis of an analysis of floating slab track system,in which the floating slabs are regarded as rigie bodies supported by elastomer bearings.By exploring the effect of the layout of floating slabs on the train-bridge coupled vibration characteristics,a reasonable layout configuration of floating slabs in the slab track system is provided.
