The urban railway has been planned not only the subway, but also the elevated railway in Seoul, South Korea. Therefore, it is steadily increasing civil complaints for railway noise passing through that residential district. In this paper, we focused on noise of squeal characteristics induced by interaction between railway vehicle’s wheel and rail. Then we selected the point that carried out scattering water droplet to the rail and compared the noise level of the watering test results before and after.
Scattering water test results showed that level of the noise reduced intermittently occurring high frequency characteristics of squeal noise as well as overall noise level.
In the future, we will apply the sensor to the sprinkling system for noise reduction where the place of existing squeal noise is, and make a suggestion of this solution will be more economical, environmental-friendly, and appropriate to reduce the squeal noise occurred by railway vehicle than others.
