Since elastic vibration of railway vehicle deteriorates the riding comfort of passengers, it is important for a lightweight high speed railway vehicle to reduce such vibration. This paper aims at analyzing the lightweight high speed railway vehicles which have elastic vibration, proposing a method of designing an vibration control system based upon of the result, and reducing not only the rigid body vibration, but also the first vertical bending mode vibra tion with active suspension. The finite element method (FEM) model of lightweight vehicle is designed, which is composed of body and bogies, and its modal analysis is performed. And it is demonstrated to reduce the vibration of both the rigid body and first vertical mode by the LQG and H_∞ control system.
