Abstract
In order to analyze the vibration performance of partially-filled liquid tank of ships, this paper takes the integration of measures including numerical simulation with finite element method and experimental verification with LMS vibration test and model analysis system of steel liquid tank under different liquid level conditions to study the fluid-structure interaction phenomenon. With the software of ADINA, the FEM model of the tank is developed and the model analysis which indicates the vibration modes and natural frequencies is completed. The simulation is compared with the experimental results which shows the natural frequency of the structure decreases with the level increases.
