【摘要】:閉合薄壁箱型構(gòu)件中各點(diǎn)的剪流為定剪流和不定剪流之和,且不定剪流在同一閉合結(jié)構(gòu)中為定值。對(duì)于單個(gè)閉合結(jié)構(gòu),受剪切后周界變形之和為零,可得到該結(jié)構(gòu)中不定剪流的計(jì)算公式。對(duì)于由多個(gè)閉合結(jié)構(gòu)組成的剖面,根據(jù)剪切變形協(xié)調(diào)原理,得到一組不定剪流計(jì)算方程。以具有兩道縱艙壁的超大型油輪為例,對(duì)船體梁剖面的剪流進(jìn)行了計(jì)算。
[Abstract]:The shear flow at each point in a closed thin-walled box member is the sum of the constant shear flow and the constant shear flow, and the constant shear flow is a constant value in the same closed structure. For a single closed structure, the sum of the circumference deformation after shear is zero, and the formula for calculating the indeterminate shear flow in the structure can be obtained. According to the principle of shear deformation coordination, a set of equations of indeterminate shear flow are obtained for sections composed of several closed structures. In this paper, the shear flow of ship beam section is calculated by taking a super large tanker with two longitudinal bulkheads as an example.
