船舶轴系静态校中有限元模型研究

Research on the Finite Element Model of Static Ship Shafting Alignment

以某型船舶轴系为研究对象,在实际轴系尺寸基础上,基于有限元法对船舶轴系静态校中时的建模问题进行研究。根据有限元简化原则,对轴系载荷进行合理处理,进而研究轴系轴承支撑的六种组合工况,建立轴系有限元模型。通过对模型施加约束和载荷,结果表明所建模型可以作为进一步校中计算的有限元模型。

Taking a certain type of ship shafting as the research object,based on the actual shafting size,the researchers make research on the modeling problems in static ship shafting alignment according to the finite element method.Based on the finite element simplicity principle,the researchers reasonably deal with the shafting load,study the six kinds of combined working conditions about the shafting bearing support,and establish the shafting finite element model.By applying the constraints and loads on the model,the research certifies that the model can be the finite element model for further alignment calculation.
