摘　　要：依据船舶轴系直线校中原理,介绍了ANSYS环境中轴系校中建模的方法和参数的设置,并在ANSYS环境中建立了轴系校中计算的有限元模型。简述了轴系直线校中法,详细说明了轴段偏中时轴系校中的状态,得出了轴段校中时轴承负荷、轴系挠度、轴系转角、轴系剪力等参数,并与轴系偏中时轴承负荷、轴系挠度、轴系转角、轴系剪力等参数做比较,得到了轴系校中参数变化规律,同时计算得出了轴段偏中产生的附加负荷对轴系校中的影响,为船舶轴系校中设计及检修提供了依据。According to principles of straight alignment of shafting,the method for modeling in the ANSYS environment and the method for setting parameters are introduced as well as FEM model for calculating in shafting alignment is established in the ANSYS environment.Then the method for straight alignment of shafting is outlined,in which shafting alignment during the shaft segment misaligning is specified.Thus parameters during the misalignment such as bearing load,shafting deflection,shafting corners,shafting shearing force is acquired.After comparing with the above parameters,the parameter variation law is obtained.At the same time,the influence of additional load occurred in the shaft segment misalignment to alignment of shafting is acquired,which provides a basis for the design and maintenance of ship shafting alignment.
