| 摘 要： | 在对具有轨道板结构的无碴轨道的分析基础上,针对连续型轨道板结构的特点,建立了连续整体型轨道板结构的力学模型,即弹性支撑的Bernoulli-Euler梁模型.通过对连续型轨道板结构质量变化对轨道和桥梁系统振动响应影响的分析,求得无碴轨道中连续型轨道板结构的质量对振动影响的规律.

| Abstract: | A dynamic modal for the continuous floating slabs is presented in this paper on the basis of an analysis of floating slab track system. In the modal,the floating slabs are regarded as the Bernoulli-Euler beams supported by elastomer bearings. By exploring the effect of the mass of floating slabs on the train-bridge coupled vibration characteristics,a characteristic of mass of floating slabs on the floating slab track system is obtained. |
