【 摘 要 】

The modal analysis and verification of super large FRP combined storage tank structure without floating roof are carried out. First, the finite element model of the structure system of the super large FRP composite storage tank without floating roof is established by ADINA. Then, the modal analysis of the structure system of the super large FRP composite storage tank without floating roof is carried out. Finally, the theoretical analysis of the sloshing frequency of the liquid storage is compared with the finite element results. The results show that the larger water storage height is, the larger the sloshing frequency is, on the contrary the larger the storage tank radius is, the smaller the sloshing frequency is. The theoretical analysis of the sloshing frequency of the super large FRP storage tank system is in good agreement with the results of the finite element calculation, and the correctness of the finite element model and the analysis method of the super large FRP composite storage tank structure system is verified. The calculation formula of the basic frequency of the storage sloshing of the super large FRP combined tank system is given.
