三弯矩方程的改进及在船舶轴系动态校中中的应用

Application of Improved Three-moment Equation in Dynamic Alignment of Ship Shafting

针对船舶轴系静态校中计算的缺点 ,对船舶轴系动态校中计算进行了理论分析 ,并对传统的连续梁三弯矩方程进行了改进 ,提出了对轴系同时进行垂直平面和水平平面校中计算的方法 ;同时 ,利用改进的三弯矩方程 ,开发了基于VB的计算软件。通过对实船轴系的校中计算与测试 ,证明是完全正确的。

In view of the defects of static alignment of shafting which is extensively adopted in the country at present, in this paper, dynamic alignment of shafting and its calculation are proposed and discussed. In the calculation, both vertical calculation and horizontal calculation of shafting alignment are put forward. At last, an example is given for the dynamic alignment calculation of a shafting that is calculated by software developed with a improved three moment equation.
