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 established according to lumped mass model,and the application program of three-dimensional visualization was developed 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 revealed 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 3D visualization graphs of midwater trawl was produced further.

Key words: fishing vessel simulator midwater level trawl lumped mass model cubic B-spline interpolation visualization
