摘　　要：以某大型集装箱船和大型油船为实例,提出了适用于轴系校中的船体变形计算原则,建立了轴系中心线相对变形的计算方法和流程.通过对轴系中心线垂向相对变形的有限元计算,研究和分析了船舶各工况时,轴系中心线变形的态势,提出了轴系校中所应计算的工况、各工况船体变形值的应用方法,并建议将反变形法用于轴系校中技术.With a very large container carrier and a very large oil tanker as calculation examples,the paper presents the calculation principle of hull deflection applying to the shaft alignment.The calculation method and procedure for the shafting center line relative deflection are set up.Through the FEM calculation for the shafting center line vertical relative deflection,a study is given to the shafting center line deflection posture under various loading cases.The suggestion is given for the loading case that should be calculated in the shafting alignment and the application method of hull deflection value in each loading cases.The anti-deflection method is suggested to be applied in the shafting alignment.
