摘要
本文从分析网片受力情况着手,建立求解网片形状和张力的微分方程组,并根据网片的特点列出差分格式。然后结合刺网网片,纲索的结构和装配情况提出初边条件,利用计算机求出每个结节的位置和网线张力,其结果与实验是相符的。
In this paper after an analysis of the stresses acting on a net, the differential equations to solve the configuration and tension of the net are established, consequently the difference equations in connection with varying characters of nets. So if the initial and boundary values corresponding with the structure and assembly of the gill net are available, the position of each knot and the tension of the net cord can be solved through numerical computations with a computer. The calculating results are quite agreable to the experimental data.
