| 摘 要： | 研究了潜艇阻抗失配基座对平面弯曲波传递的阻抑特性。基于波动理论,根据不均质结构中波型转换、阻抗特性,推导并给出了弯曲波在潜艇基座结构的透声系数及隔声量公式。在理论分析基础上,基于阻抗失配原理,对某典型基座结构进行隔振设计。数值结果表明阻抗失配基座加剧了振动波在基座中的波形转换、散射和反射。

| Abstract: | The characteristics of impedance mismatch submarine base attenuating propagation of plane bending waves are researched on the basis of wave theory.The sound transmission coefficient and transmission loss by vibration wave are deduced according to wave conversion and impedance attribute in non-homogeneous structures,and the regularity of vibration isolation performance with the base plates thickness ratio and frequency is also given.After theoretical analysis,the typical submarine base's optimized method bas... |
