| 摘 要： | 船体变形是影响船舶推进轴系校中质量的一个非常重要的动态因素.在综合考虑引起船体变形的三种主要因素的基础上,以76000t成品油轮为例,计算了极限装载状态下的重力分布和极限海况时的波浪载荷.通过对整船有限元模型合理施加重力、浮力及环境温度载荷,并模拟船舶水弹性约束,得到船体二层底的局部变形,为在轴系校中计算中计入船体变形的影响奠定了基础.

| Abstract: | The ship hull deformation has become one of the most significant dynamic influences on propulsion shafting alignment.Three major factors causing ship hull deformations are studied,and weight distributions in extreme loading conditions and wave loads in limit sea states are calculated specially for 76,000 DWT product oil tanker.Then the finite element model of the whole ship hull is constructed with gravity,buoyancy and temperature loads under elastic restraints,so that the local deformations of the double b... |
