Abstract
The response of oil tanks under dynamic loads is the key to ensuring safety, and the analysis of stiffness and strength is very necessary. Modal analysis was carried out on the oil tank to obtain the natural frequencies and vibration modes. Under specific excitation frequencies, the stress responses of the dangerous points of the front head, the rear head, the cylinder, and the transverse wave plate were calculated respectively. Three filling rates of 30 %, 50 % and 70 % were respectively selected for the structural response study, and the structural deformation and stress responses of the storage tank structure under the impact of different volumes of liquid were obtained. According to the dynamic response analysis, the structure of the front head and transverse wave plate were strengthened. It can be known from the comparison of mechanical properties that the optimized structure can significantly improve the stiffness and strength, and effectively ensure the safety of the oil tank.
