When a train is running over sharp curves, the noise is mainly caused by the flexural vibration of wheels. The noise radiating area of a spoke type wheel is smaller than that of a convensional web type wheel. Then, the spoke type wheel is supposed to reduce the noise at curves. In this paper, the characteristics of the noise radiation of the spoke type wheel is experimentally investigated, and it is found that the noise generated by the spoke type wheel is considerably smaller than that by the web type wheel. Its flexural vibration is analyzed theoretically. In this analysis, the wheel is assumed to be an annular Mindlin plate which is elastically supported by springs which simulate the spokes.
