The invention discloses a railway track structure system energy field test method and system, and belongs to the technical field of rail transit, and the method comprises the steps: arranging a plurality of acceleration sensors on a railway steel rail; dividing the steel rail by taking the arrangement position of the acceleration sensor as the midpoint of each steel rail unit to obtain a plurality of steel rail units; vertical excitation is applied above the steel rail, and an acceleration response signal is obtained through an acceleration sensor; carrying out integration processing on the acceleration response signals to obtain speeds and displacements corresponding to the plurality of steel rail units; according to the speed and the displacement, kinetic energy and potential energy corresponding to the multiple steel rail units are calculated, and an energy field corresponding to the steel rails is obtained. The acceleration sensors are arranged on the steel rails of the track, and the acceleration information of each unit of the track is measured, so that the potential energy, the kinetic energy and the total energy corresponding to each unit are obtained, the corresponding energy field is obtained, and the method is more accurate and consistent with the actual track structure.
Description
technical field [0001] The present application relates to the technical field of rail transit, and in particular, to a method and system for testing the energy field of a railway track structure system. Background technique [0002] In rail transportation, such as railways, subways and urban rails, in order to obtain the distribution of the energy field of the track structure, a specific analysis is required. Among them, in the existing technical means, the commonly used method is to establish a finite element analysis model of the track structure, and by inputting the technical parameters of each component, perform theoretical calculations, analyze and obtain the transmission and distribution characteristics of the track structure system, and then obtain the energy field. transmission and distribution laws. Among them, the accuracy of the analysis results of this method largely depends on the selection of the parameters of each component and the establishment of the simula...
