摘　　要：船舶推进轴系校中技术是保障船舶性能与安全的关键技术之一。通过对比分析刚性轴系计算法、三弯矩方程法等传统校中计算方法与有限元技术,发现有限元技术在模拟轴系弹性变形、处理复杂结构和边界条件方面优势显著。探讨了不同工况下船体变形对轴系校中的影响,结果表明船体变形会改变轴系安装基线和轴承负荷分布,影响轴系运行、寿命及传动效率。通过优化轴系校中方法,可降低轴承磨损率并提高轴系疲劳寿命。本文提出的方法为船舶推进轴系校中提供了重要参考依据。Alignment technology of ship propulsion shafting is one of the key technologies to ensure ship performance and safety. It is found that finite element technology has obvious advantages in simulating elastic deformation of shafting and dealing with complex structure and boundary conditions by comparing the traditional calculation methods such as rigid shafting method and three-moment equation method with finite element technology. The influence of hull deformation on shafting calibration under different working conditions is discussed. The results show that hull deformation will change the installation base of shafting and bearing load distribution, and affect the operation, life and transmission efficiency of shafting. By optimizing the shafting alignment method, the bearing wear rate can be reduced and the fatigue life of shafting can be increased. The method presented in this paper provides an important reference for the alignment of ship propulsion shafting.
