A Program for Predicting Wheel/Rail Rolling Noise from High-Speed Slab Railway

Wheel/rail rolling noise is considered to be one of the most important sources of railway noise, even for high-speed railways. In order to accurately predict wheel-rail noise, representative prediction program has been developed and applied. The authors have also developed a wheel/rail rolling noise prediction program, taking more account of characteristics of high-speed slab railway tracks, having sufficient computational efficiency to handle engineering problems. This paper introduces the calculation methods, operation mechanism and characteristics of this program. Typical results are given and compared with measurement.
