低騒音列車模型走行試験装置による新幹線台車部から発生する低周波圧力変動の再現

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.
