摘　　要：使用EnDyn软件,借助实船项目,尾管后轴承分别采用单支点、双支点以及多支点模型进行直线校中计算和合理校中计算,并对校中计算结果进行了对比分析。分析结果表明:不同尾管后轴承模型对靠主机主轴承负荷几乎无影响;不同尾管后轴承模型对尾管后轴轴承中螺旋桨轴心线倾斜值结果有影响。Based on the real project,the EnDyn software was used to carry out the straight and fair shaft alignment calculations with single,two and multi support points models of after stern tube bearing.Comparasion of the results were completed.The results showed that the different after stern tube bearing models did not affect the load of main engine bearings but did affect the inclination of center of propeller shaft at the position of after stern tube bearing.
