摘　　要：根据某客滚船长艉轴特性,利用船级社专业轴系计算软件,基于影响振动的轴承间距和轴承基座等主要因素的刚度进行分析,找到存在的问题并更新计算满足船级社要求。结果表明:艉轴总长度一定时,改变艉部轴承间距对叶片次转速的影响有限;当基座刚度值出现较大差异时,回旋振动临界转速变化较大。最后通过实船数据测量进行了验证,为客滚船项目轴系设计尤其是艉轴布置提供借鉴和参考。According to the characteristics of the ro-ro passenger ship’s long stern shafts,the professional shafting calculation software of the classification society is used to analyze the bearing spacing and bearing base stiffness,which are the main factors affecting the vibration,to find the existing problems and update the calculation to meet the requirements of the classification society. The results show that when the total length of the stern shaft is constant,changing the bearing spacing of the stern has a limited effect on the secondary speed of the blade;when there is a large difference in the stiffness value of the base,the critical speed of the whirling vibration changes greatly. Finally,it is verified by real ship data measurement,which provides a reference for the shafting design of the ro-ro passenger ship project,especially the arrangement of the stern shaft.
