船舶推进轴系校中计算的算法分析

Analysis of Alignment Calculation Methods for Marine Propulsion Shafting

船舶推进轴系是船舶推进装置的重要组成之一。文章对船舶推进轴系校中计算方法中的三弯矩法、力矩分配法、有限元法进行了分析和讨论，并且根据实际的应用情况，对三种算法进行了比较，最后得出结论：有限元法以及考虑动态载荷的影响是船舶推进轴系合理校中的研究方向。

Marine propulsion shafting is one of the main parts of marine propulsion plant. In the article, the calculation methods,three-moment method, moment distribution method and finite element method are discussed and analyzed. It draws a conclusion that the study about finite element method and dynamical factor should be the direction of marine shaft alignment calculation in future.
