Based on the establishment of the liquid-solid interaction vibration equation of the oil storage tank, the large-scale general finite element analysis software ANSYS was used to analyze and calculate the dynamic response of railway on-board containers under braking. The finite element model of the liquid-solid coupling system of the on-board oil tank is established, and the transient simulation analysis of the fully loaded and no-load oil storage tanks under the braking condition of the train is carried out, and the deformation diagram and the amplitude diagram of the maximum point of mean square stress at different moments of the tank during braking are drawn, and the analysis results of the fully loaded and unloaded vehicle oil storage tanks are compared. The analysis results can provide a reference for the structural dynamics design of the oil storage tank and provide a numerical basis for improving the reliability of the vehicle oil storage tank.
