Abstract

During the pass-by of Shinkansen trains in open sections, low-frequency noise is emitted from the vehicles. We have been studying the mechanisms and countermeasures for this low-frequency noise. Due to its characteristics, measurement and evaluation are challenging. In this paper, we attempted to reproduce the low-frequency noise using a low-noise moving model test facility, which can launch a 1/20 scale train model. From the test results, trends in low-frequency noise generated at the bogies of the Shinkansen vehicles were observed.
