摘　　要：为了减少传递到鱼雷自导基阵的振动能量,采用声学黑洞原理设计了一种多边形减振环结构。采用加速度振级落差表征其减振性能,开展激振器激励下的多边形结构减振性能试验研究。结果表明,多边形减振结构在50~10kHz的频率范围内具有良好的减振效果。试验结果充分说明了本文设计的多边形减振结构具有轻质、高效、宽频的减振特点,具有广泛的潜在应用价值。In order to reduce the vibration energy transferred to the torpedo homing array,a polygonal damping ring structure was designed based on acoustic black hole principle.The vibration reduction performance of polygonal structure was characterized by the drop of acceleration vibration stage,and the experimental study on the vibration performance of polygonal structure under the excitation of shaker was carried out.The results show that polygonal vibration damping structure has good vibration damping effect in the frequency range of 50~10 kHz.The test results fully show that the polygonal damping structure designed in this paper has the characteristics of light weight,high efficiency and wide frequency vibration reduction,and has a wide range of potential application value.
