不同船体构造形式在波浪载荷下的结构性能比较

摘要

船体结构形式不同,直接影响船体的结构性能和运动性能.文章针对五种船体构造形式,即:单板横向加筋、单板纵向加筋、单板双向加筋、硬壳式和夹层式这五种不同结构的船体在外载相同、质量相等的条件下进行应力与变形分析,以比较各种结构的响应和性能,为结构选型提供数值分析依据.分析考虑了静载与波浪载荷的叠加,并进行了准静态处理.通过计算和综合性能比较,挑选出既符合结构性能,又能满足使用要求的结构形式.%Ship hull in different forms has an impact on ship's structure performance and movement performance. In this paper, to five different ship structuring forms as longitudinal framing, transverse framing, combined system, hardshell form and laminated form, the stress and displacement on the condition of same loads and the equvience mass are analysed to compare the response and performance to different structures and to provide reference for structure election. The analysis considers superpositon of static loads and wave loads and deals with quasi-static. With computation and synthesis performance comparison, one structure form should be selected not only contents structure performance, but also satisfies using desire.
