This paper presents a method for reducing flexural vibrations in a railway vehicle carbody by supporting under-floor equipment using high-damping elastic mounts. This is a kind of dynamic vibration absorber utilizing under-floor equipment as a mass element which has been introduced based on the inspiration of the damping effect of passengers. A series of excitation tests were conducted in the rolling stock testing plant using a Shinkansen type test vehicle by applying the proposed method. As a result of the tests, good vibration reduction performance, including multi-modal vibration reduction and vibration isolation from the equipment, was observed.
