Abstract
In order to reduce the vibration energy transferred to the bearing plate of an undersea vehicle for detecting acoustic arrays,an accessory round plate structure for vibration reduction was designed based on the acoustic black hole principle.The vibration reduction performance was characterized by the vibration level drop of acceleration,and the vibration reduction performance tests of the bearing plate under axial and radial excitation of the shaker were carried out.The results show that the vibration reduction effect of the round plate structure is good in the frequency range of 50 Hz-10 kHz,fully showing that the accessory round plate structure designed in this paper has the vibration reduction characteristics of light weight,high efficiency,and wide frequency and has a wide range of potential application value.关键词
