MATLAB有限元方法在船舶推进轴系校中计算中的应用

Application of Finite Element Method Using MATLAB in Ship's Propulsion Shafting Alignment Calculation

船舶推进轴系安装是船舶建造中重要的一个环节,船舶轴系合理校中计算对保证轴系长期可靠运转极为重要。本文介绍了船舶轴系校中计算中常用的有限元法。依据该方法用MATLAB有限元的方法编制轴系校中计算程序,通过该程序可以计算出船舶在下水、满载或半载情况下,由于船体变形而导致轴系参数的变化。

Shipping shaft system alignment is essential to ensuring the long-term＇s reliable operation of shaft. This paper illustrates matlab finite element method is used to calculate the. shipping shaft system alignment in different conditions.Three moment methods, the transition matrix method and finite element method in shipping shaft system alignment are used, the application of finite element method in shipping shaft system alignment is proved to be more reasonable through an example.
