【摘要】 张网是我国沿海重要的捕捞作业渔具,在作业过程中受到水流与波浪的联合作用。本文应用有限元方法与集中参数法建立了张网在波流场中的动力学方程,以预测张网在波流作用下的水动力学特性。将数值计算结果与水槽模型实验结果进行比较,符合良好,表明本方法可以在一定程度上代替传统的水槽模型实验,为张网渔具设计和优化提供一种可供选择的数值分析方法。更多还原

【Abstract】 Stow net is an important fishing gear in the inshore fishery in China.Its movement subjects to the effects of current and wave in fishing operation.In this paper,the finite element method and lump parameter method were employed to construct the dynamic equation of stow net in wave and current for predicting the hydrodynamic charecteristics of stow net in combined wave and current.Numerical calculation results agreed well with the experimental results from flume model test.The numerical method developed in this study can be used for stow net designing and optimization,replacing traditional water tank experiment to some extent.更多还原
