Analysis of Total Vibration Characteristics of Large Cruise Ship Based on Super-element Method
In this paper,the numerical prediction method of the total vibration of large cruise ships was studied,and the super-element method is applied to the total vibration analysis of large cruise ships,and the advantages of the super-element method compared with the traditional direct calculation meth-od were compared and analyzed.The effects of the establishment mode,the number of super-element models and the selection of residual structures on modal results and computational efficiency were dis-cussed.The results show that the super-element method is more applicable to the total vibration anal-ysis of large structures such as cruise ships.By choosing the appropriate super-element division meth-od and number,the calculation accuracy can be ensured and the calculation efficiency can be improved.
