摘要
在对具有预制式轨道板的无蹅轨道分析的基础上,针对预制式轨道板结构的特点,建立了预制式轨道板结构的力学模型(即刚体模型).通过对预制式轨道板不同纵向布置对轨道和桥梁系统振动响应影响的分析,得到了无蹅轨道中预制式轨道板的合理布置方式.
A dynamic model for the prefabricated floating slabs was presented on the basis of analysis of a floating slab track system.In the model,the floating slabs are regarded as rigid bodys 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 on the floating slab track system was obtained.
