本文提出了一种用计算机模拟分析围网渔具性能的新方法。在动力学仿真方面，利用运动方程模拟了渔具在射击和追逐过程中在空间运动时的形状和运动。首先，应用质点-弹簧模型，建立了系统的运动方程。其次，我们开发了一个仿真工具，可以自动生成一个齿轮设计图纸的数学模型。第三，采用求解非线性方程组的隐式方法进行计算。第四，通过实测数据与计算数据的对比，验证了仿真所用数学模型的准确性。最后，使用以各种方式装配的齿轮进行模拟。(C)2007 Elsevier B. V.保留所有权利。
This paper presents a new approach to the analysis of the performance of purse seine fishing gear using a computer simulation. For dynamic simulation, the equation of motion was used to model the shape and movement of the fishing gear as it moved through space during the operations of shooting and pursing. First, a mass-spring model was applied and the equation of motion was described. Second, we developed a simulation tool that can automatically generate a mathematical model from a gear-design drawing. Third, an implicit method for solving nonlinear equations was applied to the calculation. Fourth, the accuracy of the mathematical model used in the simulation was verified by comparing measured and calculated data. Finally, simulations were made using gear rigged in various ways.
