| 摘 要： | 为了在渔船模拟器中进行中层拖网的动态仿真，首先利用等效网面方法对中层拖网进行简化，然后根据集中质量法建立了中层拖网的水动力模型，并开发了中层拖网的三维可视化程序。利用三次B样条插值曲线绘制中层拖网，并采用纹理映射技术提高中层拖网三维可视化的效果。对一中层拖网进行了仿真研究，结果表明：仿真结果同其水槽试验结果相近，最大误差在20％以内，验证了该模型的合理性。最后，文中还给出了中层拖网的三维可视化效果图。

| Abstract: | A midwater trawl was simplified first by an equivalent method, then a hydrodynamic model was estab- lished according to lumped mass model, and the application program of three-dimensional visualization was devel- oped to simulate dynamic behavior of midwater trawl in fishing simulator. Cubic B-spline interpolation and texture mapping were used to improve visualization effect of midwater trawl. The simulating study on a midwater trawl re- vealed that simulation results were similar to those of flume experiment with a maximum error of 20% , and that the established hydrodynamic model was acceptable. A 3 D visualization graphs of midwater trawl was produced further. |
