Abstract: In order to solve the problem of poor simulation accuracy of the traditional method for the coupled vibration of high-speed railway track, a discrete element simulation method for the coupled vibration of high-speed railway track under load is proposed. Based on the coupled vibration equation of high-speed railway track, the coupled vibration equation of high-speed railway track is built on the basis of determining the vector and parameters. The discrete element model is used to analyze the coupled vibration of high-speed railway track under the action of load, and the results of the discrete element simulation experiment of the coupled vibration of high-speed railway track are obtained. In order to verify the simulation accuracy of the proposed discrete element method, a comparative experiment is designed. According to the experimental results, the proposed discrete element simulation method for coupled vibration of high-speed railway track under load greatly improves the simulation accuracy. In the 100th experiment, the simulation accuracy of this method is as high as 93%. The coupling vibration discrete element simulation method has better simulation effect.
