THE ANALYSIS AND CONTROL OF ROLLING NOISE IN URBAN RAIL TRANSIT SYSTEMS
When an electric-powered steel wheel transit vehicle moving on straight, continuously welded rail passes an observer, the predominant noise heard is rolling noise. This is the noise produced by small-scale roughness on the running surfaces of the wheels and rails. The minute peaks and valleys of the surface roughness excite both the wheels and the rails, which in turn radiate a characteristics broadband noise. Before cost-effective control of this noise can be developed, the mechanism for its generation must be clearly understood. The study reported here undertook to develop analytical empirical formulas for the prediction of rolling noise that contain all the important parameters describing the wheel/rail dynamic system.
