本文针对轨道交通和高速铁路中广泛采用的无砟轨道结构,对无砟轨道的轨道板结构的分析基础上,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,即弹性支撑的刚体模型。通过对预制式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,求得无砟轨道中预制式轨道板结构的质量对振动影响的规律,提出了无砟轨道结构减振设计的优化方案。
In this paper, based on the analysis of ballastless track structure widely used in rail transit and high-speed railway, based on the analysis of ballastless track plate structure, the mechanical model of prefabricated rail plate structure is established according to the characteristics of prefabricated rail plate structure Flexible support of the rigid body model. Through the analysis of the influence of the mass of the prefabricated track plate on the vibration response of the track and the bridge system, the influence of the prefabricated track plate structure quality on the vibration is obtained, and the optimization of the anti-vibration design of the ballastless track structure Program.
