随着中国高铁建设进程的不断推进,高铁车站的振动问题变得越来越突出,而与之相关的研究却较少.针对高铁车站直通线路车速较快的特点,建立了不同形式的直通线路-浮置板模型.从研究减振性能的角度出发,分析了浮置板模型的基频;从确保行车安全的角度出发,分析了在移动荷载作用下钢轨的最大位移和振动特点.结果表明,应用于高铁车站直通线路的浮置板结构应选取单板形式,并应适当地增加弹簧刚度和浮置板厚度等参数,以保证行车安全和减振效果.
With the continuous development of China’s high-speed railway construction, the vibration problems of high-speed railway stations have become more and more prominent, and the related researches are few. In view of the fast speed of the expressways of the high-speed rail stations, different forms of direct- - Floating plate model.From the perspective of the study of vibration reduction performance, the fundamental frequency of the floating plate model is analyzed.From the point of ensuring traffic safety, the maximum displacement and vibration characteristics of the rail under moving load are analyzed.The results show that The floating plate structure applied to the direct transmission line of high-speed railway station should be of veneer type, and parameters such as spring stiffness and floating plate thickness should be appropriately increased to ensure the traffic safety and damping effect.
