In recent years, it is important to decreasing the railway noise. In the railway noise, there are rolling noise, motor noise, and aerodynamic sound. At the low-speed train, the rolling noise is one of major source of the railway noise. But it is not clear the noise generating mechanism. In the recent research, it is estimated the rolling noise of wheel by using vibro-acoustic interaction analysis. However, it is very difficult to estimate the noise property of the only wheel. In this paper, we describe the estimation of the rolling noise property using the rolling test machine establishment of vibro-acoustic analysis using finite elements analysis and boundary elements analysis.
