摘　　要：以厚壁圆筒理论为基础,分析艉管轴承压装过程中的应力和应变,推导总过盈量和接触压力的计算公式,并对比国内船标和各国外厂家计算公式的差异。以某项目为例,进行对比计算,并给出相关建议。Based on the theory of thick-walled cylinder,the stress and strain of the stern tube bearing during the pressing and assembling procedure were analyzed,and the calculation formulas of the total interference and contact pressure were deduced.The differences between the calculation formulas of the marine standard and the foreign manufacturers were compared.Taking a project as an example,the calculation was carried out and the relevant advice was given.

关 键 词：艉管轴承 过盈压装 厚壁圆筒
