摘　　要：本文研究当水下航行器外壳体振动传感器总数确定之后,如何利用这有限个数的传感器得到更多航行器壳体振动信息,从而更准确地评估航行器当前声隐身状态的问题。基于结合声辐射模态理论,给出传感器优化配置方法和步骤,并利用类似水下航行器的椭球壳体结构作为研究对象进行仿真,对该方法进行验证。研究结果表明,针对类椭球结构的水下航行器,低频段壳体传感器应布置在两端及中间位置。The problem of how to arrange the sensors on the shell of the underwater vehicle aimed to assess the vehicle acoustic stealth situation better was researched.With the use of acoustic radiation mode theory,the method and steps of optimal sensor placement has been put forward.The simulation analysis of a quasi-elliptic shell structure similar to the common underwater vehicle has been given to validate the method in addition.The results showed that aimed at low frequency band the sensors should be located on the both ends and intermediate position of the structure.
