定常流作用下垂直阵线形预报及测量

Prediction and monitor of vertical array in steady stream

在工程应用中,通常采用悬挂重物的方式减少垂直阵因水流作用所产生的偏角。本文建立了垂直阵的阵形预报模型,采用微元分解及循环迭代的计算方法对长垂直阵在水流作用下的形变作出预报。另外还设计了一套用于现场监测阵形的声学方法,并在实测中采用该方法对预报模型进行了验证。结果表明预报模型是准确的,可以在实际的测试中应用,并指导阵形设计和工程布放。

In the application of vertical array,the offset angle caused by stream is reduced by hanging a heavy object.The model to predict the line style in stream is dealt with in this paper.The different method and iteration algorithm are used in the model,and an underwater acoustic method is given to monitor the line style in real time.Both of the predict model and the method of monitor are used in a practice test,and the result illustrates the accuracy of the predict model and its utility in the design and application of vertical array.
