摘　　要：设计了模型试验的结构形式、动力条件以及试验所用的网衣和沉子的规格,通过物理模型试验及数值简化计算,得到了相关数据,分析了沉子的不同配重对六边形无节单片尼龙网衣水阻力及变形的影响,推导出网衣水阻力与沉子质量的相关经验公式,给出了网衣顶端倾角、底端位移与沉子质量相关的计算方法。The overall structure, dynamic conditions and sizes of the nets and sinkers in the model test were well designed in order to analyze the influence of different sinker weights on water resistance and net deflection for hexagonal knotless single nets. The relation of sinker weight to water resistance, and the net's top incidence and bottom displacement can be obtained by using the empirical equations derived in the paper.
