Steel railway bridges characteristically tend to generate high-level structure-borne noise. The authors have developed a method to predict structure-borne noise based on the analysis of flexural vibration of plate, however it possesses a drawback that it is difficult to calculate directly the exciting force generated by contact of wheels with rail. On the other hand, recently new methods are developed to analyze dynamic interaction between rail and wheels by modeling the rail as an Euler's beam supported discretely at constant interval, and assuming sinusoidal surface irregularity of rail. So we tried to apply this method to analysis of rail vibration response on steel railway bridge and examine to combine this method with above-mentioned method for prediction of structure-borne noise.
