摘要
依据渔具模型水槽试验,分析讨论影响网囊网目扩张性能的不同因素的影响机制。通过图像处理和数据分析,观测模型网的水阻力情况和不同情况下网囊网目的扩张情况;确定了不同改进措施下,网囊网目张开角度的变化情况和网囊不同位置网目张开角度的差异性,同时结合网囊水阻力的变化进行分析研究。
This study was on the basis of the Fishing gear hydrodynamic modeling experiment in laboratory flumes. Analyse and discuss the different influenced factors for mesh expansion-performance. We researched the hydraulic resistance and mesh expansion-performance of different working conditions by using image processing and data analysis. The changing of screen angle with different corrective measures and the diversity of different position of the cod-end, combining with the changing of the hydraulic resistance were analyzed.
