项目摘要
A study to develop a midwater trawl system which is highly controllable was conducted. Three approaches were made to conduct the study namely ; flume experiment, field experiment and theoretical analysis.The flume experiment was conducted to clarity the performance of the midwater trawl net using a new net-mouth opening device made of canvas by comparing its static and dynamic characteristics to that of the otter type. It was observed that the canvas type midwater trawl net was suited to low speed towing because its mouth opening area relative to the total drag of the gear was high at low speed. The control performance of both types of midwater trawl based on the working depth was compared by changing the current speed. The result showed that the time required to control the working depth at the same floating or sinking distance was shorter for the canvas type than the otter type.The field experiment was conducted on board the R/V Shinyo-maru of Tokyo University of Fisheries at Wakasa … More Bay in Japan Sea in 1989 and 1990. The time series data of the working depth of the net, the height of the net-mouth, the wing spread, the tension fo the bridle, the depth of the otter boards, etc. were observed at variable towing speed and warp length.The theoretical analysis was done by designing an experimental formula for calculating the net drag of the midwater trawl. The theoretical analysis was based on the midwater trawl system of the R/V Shinyo-maru. Good agreement was obtained between the experimental and the theoretical results.Lastly, an autoregressive model to estimate the dynamic behavior of midwater trawl system by varying the towing speed was built and unknown parameters in the model were determined. The validity of the present model was statistically proven. A computer simulation was made on the model to compare it with the results of the field experiment. Similar characteristics of the dynamic behavior of the midwater trawl system for the model and the field experiment was obtained. Less
进行了开发高度可控的中层拖网系统的研究。本文通过水槽试验、现场试验和理论分析三种方法进行研究,其中水槽试验采用新型帆布开口器,通过与水獭式网的静态和动态特性的比较,明确了拖网的性能。结果表明,帆布式中层拖网适合于低速拖曳,因为其开口面积相对于渔具的总阻力在低速时较大。通过改变海流速度,比较了两种中层拖网基于作业深度的控制性能。结果表明,在相同的浮距或沉距下,帆布型比水獭型控制作业深度所需的时间短。 ...更多信息 1989年和1990年在日本海。在不同拖速、不同经长条件下,观测了网的工作深度、网口高度、网翼张开度、张索张力、网板深度等时间序列数据,并设计了中层拖网网阻力的实验计算公式,进行了理论分析。理论分析是基于R/V Shinyo-maru的中层拖网系统。最后,建立了随拖速变化的中层拖网系统动力学行为的自回归模型,并确定了模型中的未知参数。该模型的有效性在统计上得到了证明。对模型进行了计算机模拟,并与现场试验结果进行了比较。模型试验和现场试验结果表明,中层拖网系统的动力学行为具有相似的特征。少
