| 摘 要： | 抗冲瓦能够很好地实现对水下非接触爆炸载荷的整体冲击隔离.其特殊的空腔结构是否同时具有隔声性能也广为关注,为此,在某海域港湾内对一艘试验船进行了敷设与未敷设抗冲瓦的声辐射噪声对比试验.试验结果表明,抗冲瓦在广泛的频域内均具有良好的隔声性能.舰艇湿表面敷设抗冲瓦对舰艇本体噪声向水中辐射的抑制效果量级为:0.1～1 kHz频段约为5 dB:1～3 kHz约为10 dB;3 kHz以上15 dB,能够较大地降低舰艇的水中辐射噪声,为提高舰艇整体的隐身性能提供了一种新的技术和方法.

| Abstract: | A new concept of ship anti-shock layer based on the impedance mismatch theory is developed by Naval Academy of Armament and Shanghai Jiao Tong University together.The underwater non-contact explosion loads can be isolated by the ship anti-shock layer very well.But the sound isolation performance caused by rubber material and the special cavity structure of the ship anti-shock layer was also concerned.The comparison experimental for sound radiation noise between a ship covered with and without the anti-shock... |
