Abstract
Under the braking condition of the tanker, the liquid in the tank will have an impact on the tank body due to shaking. The arrangement spacing of the wave-proof plate has a great influence on the wave-proof effect. In order to study the optimal spacing of the wave-proof plate, a liquid sloshing model was established based on FLUENT, and the stress peak of the front head and the wave-proof plate 1 was determined as the optimization goal. The response model of the front head and the wave-proof plate 1 on the space of the three wave-proof plates was obtained through the response surface experiment, and the multi-objective optimization mathematical model of the wave-proof plate spacing was established based on RSM. The NSGA-II algorithm was used to solve the model, and the optimal combination of parameters of the spacing of the wave-proof plate was obtained. After optimization, the peak stresses of the front head and the first wave board are reduced by 8.6% and 5.2%.
