Carbody elastic vibration of a railway vehicle negatively affects the ride comfort of passengers. One of the sources of the vibration is excitation force induced by the longitudinal vibration of the bogies. The excitation force transmits to the carbo

Vertical vibrations in railway vehicles are not only induced by track irregularity but also affected by the rotation of wheelsets with small mass imbalance. It is known that the excitation force generated by the rotation of wheelsets is transmitted f

In order to investigate the vibration characteristics of railway vehicle carbodies, some sorts of analytical models have been proposed, such as simple beam, box-type, and finite element models. These models are constructed based on the equations of m

This paper presents a method for reducing vertical vibrations in a railway vehicle carbody by supporting underfloor equipment using high-damping elastic mounts. This is a kind of dynamic vibration absorber utilizing underfloor equipment as a mass ele

This paper presents an analytical method for in-plane and out-of-plane coupled vibration in thin curved panels. To treat such vibrations simply, a structure consisting of the combination of straight and curved beams is proposed and the connecting con

It has been shown that passengers have large reduction effect on the elastic vibration of a railway vehicle car body. That effect is considered due to the viscoelastic motion and multi-directional motion of a human body. This study focuses on the lat

It is one of the important issues to investigate the vibration behavior of railway bogies, since the vibration of the bogies may result in loosening bolts which fix the parts to the bogie frames or/and fatigue fracture of the parts themselves. A tech

It is pointed out that the yaw dampers, which are often installed in between carbody and bogie frame of a high-speed railway vehicle, have such unfavorable points that the damping force is generated not only in the yawing direction but also in other

Piezoelectric elements, which are electrically connected to external shunt circuits, are introduced to suppress bending vibration of a scale model of a railway vehicle. The authors proposed two types of shunt circuits aiming at practical use. One cir
