The invention discloses a track board system energy field test method and system, and belongs to the technical field of track traffic. The method comprises the following steps: arranging an acceleration sensor on a track board; dividing the track board by taking the arrangement position of the acceleration sensor as a central point of each track board unit to obtain a plurality of track board units; vertical excitation is applied to a steel rail above the track plate, and an acceleration response signal is obtained through an acceleration sensor; carrying out integration processing on the plurality of acceleration response signals to obtain the corresponding speed and displacement of the track slab unit; and according to the speeds and displacements corresponding to the multiple track slab units, kinetic energy and potential energy corresponding to the multiple track slab units are obtained through calculation, and then an energy field corresponding to the track slab is obtained. The acceleration sensors are arranged on the track plates of the track, the acceleration response signals of all the track plate units are measured, the corresponding energy field is obtained, and the energy field 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 an energy field of a rail slab 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 simulation model. Fo...
