In China, the construction of passenger dedicated line is in progress on a large scale. As the important infrastructure of passenger dedicated line, the fastener damping of ballastless turnout influences the vibration and noise of the track. In order to study the mutative fastener damping’s impact on the vibration and noise of ballastless turnout, The method for determining the fastener damping was established by using the vehicle-turnout coupling dynamic analysis, and the noise prediction method for ballastless turnout was stated from three parts of the excitation of wheel-rail roughness, the sound radiation efficiency and the calculation of wheel-rail radiated noise. From both aspects of vibration decrease and noise reduce, the reasonable fastener damping of ballastless turnout was determined by using the above method. The research results showed that the damping of 0.15~0.225 to the fastener of ballastless turnout was reasonable for vibration decrease and noise reduction.
