Abstract:
1. A vibrational component acceleration estimation device for a railway vehicle for estimating the acceleration of a vibrational component acting on a vehicle body in a lateral direction when the railway vehicle having a vehicle body tilting device runs in a curve section, comprising: an acceleration detection means for detecting the acceleration acting on the vehicle body in a lateral direction; a theoretical excess centrifugal acceleration calculation means for acquiring track information at a running point of the railway vehicle, a running speed of the railway vehicle, and ON/OFF information of vehicle body tilting operation, and calculating a theoretical excess centrifugal acceleration αL acting on the vehicle body in a lateral direction based on the following Equations (1) or (2); and a vibration acceleration calculation means for deriving the acceleration of the vibrational component acting on the vehicle body based on the acceleration detected by the acceleration detection means and the theoretical excess centrifugal acceleration αL determined by the theoretical excess centrifugal acceleration calculation means, the vibration acceleration calculation means further processing a signal indicating the derived acceleration of the vibrational component through a high-pass filter, in the case where the vehicle body tilting operation is turned ON: in the case where the vehicle body tilting operation is turned OFF: where in the above Equations (1) and 2), η
