中文摘要：

为决定钓鱼的网配置和负担的一个数字模型被开发，基于 lumped 群众方法。模型被用来在等速流由不同铅锤重量在严肃海笼子的网上分析影响。严肃海笼子的网在不同的临和铅锤重量下面被模仿。以便验证数字结果的有效性， Lader 和 Enerhaug 做的模型试验结果被引用并且与数字的相比。数字模拟的结果同意有试验性的和协议的井在不同速度和铅锤重量下面在 13% 的一个错误范围以内。Thenumerical 结果显示增加铅锤重量能有效地减少网变丑，而是总数因此在网愿望增加以后拖力量。结果将为严肃海笼子的水动力学行为的更好的知识给参考书。

英文摘要：

A numerical model for determining fishing net configuration and load is developed, based on the lumped masses method. The model is used to analyze the influences on the net of gravity sea cage by different sinker weights in uniform flow. The net of gravity sea cage is simulated under different current velocities and sinker weights. In order to verify the validity of the numerical results, model test results made by Lader and Enerhaug are cited and compared with the numerical ones. The results of numerical simulation agree well with the experimental ones and the agreement is within an error range of 13% under different velocities and sinker weights. The numerical results indicate that increasing the sinker weight can effectively reduce the net deformation, but the total drag force on the net will increase accordingly. Results will give references for better knowledge of the hydrodynamic behavior of gravity sea cage.
