Mechanism of Wheel/Rail Noise for Rail Transit

Wanming Zhai

Abstract

In recent years, with the raising of train speed, the construction of the fast passenger line, and the development of high-speed railway and mass rail transit, wheel/rail noise is paid attention greatly in China. On the basis of the theory of vehicle-track coupling dynamics and noise radiation and propagation, mechanism of wheel/rail noise is analyzed. Further more, the basic rule of wheel/rail noise is presented.
