Autor: Ken-ichiro AIDA, Yuki AKIYAMA, Tadao TAKIGAMI, Takahiro TOMIOKA, Takefumi MIYAMOTO, Daichi NAKAJIMA

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 89, Iss 924, Pp 23-00129-23-00129 (2023)

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

Reduction of vertical vibration of railway vehicle with high-damping elastic support of underfloor equipment

Autor: Ken-ichiro AIDA, Yuki AKIYAMA, Tadao TAKIGAMI, Takahiro TOMIOKA

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 87, Iss 902, Pp 21-00075-21-00075 (2021)

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

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 85, Iss 875, Pp 18-00453-18-00453 (2019)

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

Development of a new mounting structure of yaw damper to reduce railway carbody vibration

Autor: Daichi NAKAJIMA, Ken-ichiro AIDA, Yuki AKIYAMA, Tadao TAKIGAMI, Takahiro TOMIOKA, Yukio NISHIYAMA, Takayuki TANAKA, Takefumi MIYAMOTO, Norihiko IMAOKA

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 83, Iss 854, Pp 17-00078-17-00078 (2017)

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

Reduction of flexural vibration of railway vehicle carbody by using elastic torus (Validation of vibration reduction effect using actual railway vehicle and numerical investigations on the vibration reduction mechanism)

Autor: Takahiro TOMIOKA, Satoshi TACHIKAWA, Yuki AKIYAMA, Ken-Ichiro AIDA

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 83, Iss 846, Pp 16-00342-16-00342 (2017)

A new vibration reduction device against flexural vibration of railway vehicle carbody utilizing deformation of a donut-shaped elastic body called elastic torus is presented in this paper. The vibration properties of the elastic torus specially desig
