水下航行载体实航振动和噪声测量装置的研究

Development of a Vibration and Noise Measuring Apparatus for an Underwater Vehicle

介绍了一种新型的水下航行载体实航振动和噪声测量装置，它包含一个多通道、连续高速采样、大存储容量的ＤＡＴ数字磁带记录仪。这套装置体积小，安装在水下航行载体内部，用可充电电池供电，自成独立系统。它不仅能测量实航全过程的振动和噪声，还能记录其他瞬态或稳态参数，具有很大的通用性。

A new apparatus used to measure the vibration and noise of an underwater vehicle is developed.It contains a multichannel DAT digital tape recorder with high speed,continous sarrpling and large storage capacity.The apparatus powered by rechargeable batteries and installed on board is an indeperdent system and can be commonly used not only to measure the vibration and noise in the whole process of a test but also to record the other transient and stationary parameters.
