【摘要】：闭合薄壁箱型构件中各点的剪流为定剪流和不定剪流之和,且不定剪流在同一闭合结构中为定值。对于单个闭合结构,受剪切后周界变形之和为零,可得到该结构中不定剪流的计算公式。对于由多个闭合结构组成的剖面,根据剪切变形协调原理,得到一组不定剪流计算方程。以具有两道纵舱壁的超大型油轮为例,对船体梁剖面的剪流进行了计算。
[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.
