BODY INCLINATION ANGLE DIAGNOSING DEVICE AND BODY INCLINATION ANGLE DIAGNOSING METHOD

PROBLEM TO BE SOLVED: To provide a body inclination angle diagnosing device for detecting an abnormality of an inclination angle of a body of a rolling stock, and a body inclination angle diagnosing method. SOLUTION: This diagnosing device is provided with a detection means 2 for detecting acceleration αF in the horizontal direction acting on the body B of the rolling stock T for the direction of the advance of the rolling stock, a theoretical over-centrifugal acceleration computing means 3 for obtaining theoretical over-centrifugal acceleration αL in the horizontal direction acting on the body B for the direction of the advance of the rolling stock during steady curve section traveling based on information about a track, a speed V of the rolling stock, and the inclination angle θ of the body, and an abnormality detection means 4 for detecting the abnormality of the inclination angle θ for a bogie W of the body B based on the acceleration αF detected by the detection means 2 during steady curve section traveling and the theoretical over-centrifugal acceleration αL obtained by the theoretical over-centrifugal acceleration computing means 3.
