城轨道岔减振降噪功能的研究

Research on vibration and noise reduction function of urban rail transit turnout

针对城市轨道交通道岔区减振降噪问题,从道岔平面线型设计、岔区刚度均匀化、岔区无缝化、研发新型减振扣件等方面采取策略,开发减振降噪效果优良、零部件寿命长、施工便利、少维护等优点的新型城轨减振道岔,为城轨线路周边居住的人们提供宁静和谐的生活环境。

In order to solve the problem of vibration and noise in the urban rail transit turnout area,measures are taken from the geometric design of the turnout,the stiffness homogenization in the turnout area,the jointlessness in the turnout area,and the development of new anti-vibration fasteners. The new anti-vibration turnouts for urban rail transit are developed with advantages such as excellent vibration and noise reduction effect,long service life of components and parts,convenient construction and less maintenance,which provide a quiet and harmonious living environment for people living around the urban rail lines.
