Application of Transfer Path Analysis to the Structure Borne Sound from a Bogie of Railway Vehicle

Abstract

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.
