Abstract
To realize an accurate evaluation of the riding quality of a railway vehicle In a riding quality simulation system (1), a control unit (60) controls a drive unit (50) such that vibrations along a plurality of axes arbitrarily selected among six axes can be simultaneously applied to a simulated passenger room (10) simulating an interior of a railway vehicle. The control unit (60) makes control in such a manner that, among an up-down component, a left-right component, and a forward-backward component of the vibration applied to the simulated passenger room (10), upper limits of vibration acceleration and frequency range of the forward-backward component are made smaller, thereby making higher upper limits of vibration acceleration and frequency range of the up-down and left-right components. According to this riding quality simulation system (1), when the vibration is separated into the up-down, left-right, and forward-backward components, an extremely bad riding quality can be reproduced with respect to each component, thereby allowing an accurate evaluation of the riding quality.
