本文旨在研究渔网在水流中的形态和张力分布。基于集中质量法建立了简化网络的数值模型。建立了每个集中质量的运动方程。采用龙格-库塔-弗纳五阶和六阶方法求解这些联立方程组,得到各集中质量的位移和张力。为了验证数值方法的有效性,进行了模型试验。数值模拟结果与实验结果吻合较好。
The aim of this paper is to investigate the shape and tension distribution of fishing nets in current. A numerical model is developed, based on lumped mass method to simplify the net. The motion equation is set up for each lumped mass. The Runge–Kutta–Verner fifth-order and sixth-order method is used to solve these simultaneous equations, and then the displacement and tension of each lumped mass are obtained. In order to verify the validity of the numerical method, model tests have been carried out. The results by the numerical simulation agree well with the experimental data.
