穿浪双体船横向强度与扭转强度的有限元计算

穿浪双体船的连接桥在横浪和斜浪中遭受比较大的横向弯矩和扭转力矩的作用,其自身的强度对穿浪双体船的安全性来说至关重要。本文在有限元理论的基础上,采用直接计算方法对一艘穿浪双体船进行了横向强度和扭转强度的整船有限元分析,对其总强度进行了校核,并初步分析了该船上层建筑对总横强度的影响。通过对计算结果的分析,掌握了该船的应力分布,为结构优化设计提供依据。

Finite Element Analysis on the Transverse and Torsion Strength of a Wave Piercing Catamaran

The cross-structures of wave piercing catamaran (WPC) are subjected to large transverse bending moment and torsion moment under transverse and oblique waves. Its strength is critical to its safety. Based on the finite element analysis (FEA),direct computation was performed on a full FEA model of WPC to obtain its transverse and torsion strength,and then to check its global strength. The preliminary study was conducted on the effects of the top structures on the global transverse strength. Through analyzing ...
