伝達経路解析の鉄道車両の台車系固体伝搬音への適用

抄録

To take countermeasures effectively against the interior noise of the railway vehicle, it is important to comprehend the transfer paths. The purpose of this study is to apply the Transfer Path Analysis (TPA) to the structure borne sound from the bogies of the railway vehicles and to clarify the contribution ratio according to the transfer paths. In this paper, we describe the contribution ratios by applying the TPA to the vibration transfer paths from the bogie to the floor in the actual Shinkansen running tests.
