A method for measuring wheel load data of a railway vehicle under different track twisting conditions

The invention relates to test methods for urban rail transit vehicles and specifically provides a method for measuring wheel load data of a railway vehicle under different track twisting conditions. The method is implemented by means of a moving test tool. The moving test tool comprises a location pedestal fixed on a track; the upper portion of the location pedestal is successively provided with force sensors and an upper pressing plate; the force sensors are in control connection with a control terminal; a test wedge is detachably mounted on the upper pressing plate. The test wedge can realize height change between wheel sets so that the working condition of track twisting can be simulated. Compared with conventional wheel load reduction test methods for subway vehicles, the method is applicable to the load reduction tests for various kinds of railway vehicles, is not restricted by vehicle structures and has greatly-improved applicability and practicability.
