摘要
本文针对大型邮轮总振动数值预报方法展开研究,将超单元法应用于邮轮总振动分析中,对比分析超单元法相比传统直接计算方法在大型邮轮总振动分析中的优势,探讨超单元模型建立方式、设置数量以及残余结构选取对模态结果及计算效率的影响.结果表明:超单元法在邮轮这类大型结构总振动分析中具有更强的适用性,选用合适的超单元划分方式及数量可在保证计算精度的同时提高计算效率.
Abstract
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.
