摘　　要：以某浮船坞的典型舱段为研究对象,按中国船级社2009年《浮船坞入级规范》,采用有限元直接计算法对该船主要结构构件的屈服强度进行计算校核,对浮船坞建立全船有限元模型、“1/2+1+1/2”舱段有限元模型、舷伸甲板局部结构有限元模型,并分别进行总纵强度、横向强度及局部结构强度直接计算,各板的相当应力、剪力及骨材的应力均小于规范要求的许用应力,故该船结构强度满足要求。Taking a typical tank floating dock section as the research object,by the China classification society in 2009,the floating dock classification standard,by using the ship main direct calculation method of finite element calculation and checking the yield strength of the components,the floating dock ship finite element model is set up,“1/2+1+1/2”section of the finite element model,sponson deck local structure finite element model,and the longitudinal strength,transverse strength and direct local structure strength calculation,the equivalent stress of each plate,shearing force and stress of the aggregate are less than the allowable stress of specification requirements,so the ship structural strength meet the requirements.
