The invention relates to the field of noise measurement, in particular to a self-noise measurement method based on an underwater glider. According to the invention, an underwater glider electric control system, an acoustic data acquisition system and a single-channel hydrophone are integrated to form a self-noise measurement system of the underwater glider. The single-channel hydrophone is placedin a stern streamline fairing to receive mechanical noise data, a stern cabin integrated acoustic data acquisition system adds a time label to the received data and stores the data, and the mechanicalnoise of the platform is more effectively extracted and researched by using a silencing pool. The method effectively measures and analyzes the self-noise of the glider, not only is the premise of ensuring the glider to perform marine observation, but also can be used for guiding correct implementation of vibration and noise reduction measures of the glider and assisting acoustic design and noiseprediction of an underwater noise system.
本发明涉及噪声测量领域,具体说是一种基于水下滑翔机的自噪声测量方法。本发明将水下滑翔机电控系统、声学数据采集系统以及单通道水听器进行集成,组成水下滑翔机的自噪声测量系统。将单通道水听器放置于艉部流线型的导流罩中进行机械噪声数据的接收,艉部舱段集成声学数据采集系统将接受到的数据添加时间标签并进行存储,利用消声水池对平台的机械噪声进行更加有效的提取研究。该方法对其自噪声进行有效的测量和分析,不仅是保证滑翔机进行海洋观测的前提,而且还可用于指导滑翔机减振降噪措施的正确实施与辅助水下噪声系统的声学设计和噪声预报。
