| 摘 要： | 利用多输入多输出(MIMO)量化分析模型对潜艇潜在故障源进行分析,并通过频段因果性检测解决M IM O模型各输入源的优先权问题,从而方便地得到了各源相对于叠加场的贡献百分比动态曲线,以用于潜艇声学故障的预报.给出了潜艇声学故障预报的一般流程,并阐述其应用步骤.用一个水池实验验证了文中所提出的方法的可行性.

| Abstract: | The concept of submarine acoustic fault and its prediction is brought forward for the first time.Based on the causality checking of inputs,the multi-input/multi-output(MIMO) modeling is employed to analyze and obtain the contribution per cent curve of each noise source,and thus to predict acoustic fault.Then a general flow and process of acoustic fault prediction is also given.Finally,a model ship towing tank experiment validates the feasibility of the proposed method. |
