为了提高水面舰船的声隐身性能，本文对典型的舰船基座结构开展研究。利用阻抗分析法研究了基座结构的输入机械阻抗对舰船声隐身性能的影响，基于有限元方法分析了典型舰船基座结构参数的变化对其输入机械阻抗的影响规律。研究表明：基座面板的厚度和隔振器的布置位置对机械阻抗的影响较大，腹板的厚度和高度、腹板开孔和开孔加强对机械阻抗的影响较小。研究所得的结果对舰船基座的设计有一定的指导意义。

In order to improve the sound stealth technology of naval vessels, this article researched the typical base for ship. Using the impedance analytic method, the influence of impedance characteristics of typical base to the sound stealth technology of naval vessels is studied. Based on FEM method, the effects of base structure parameters on impedance characteristics is researched. Research shows that, the thickness of panel and vibration isolator′ s location have a great influence on the impedance characteristics, the thickness and height of web, hole on web and strengthened hole have little influence on the impedance characteristics. A series of valuable conclusions are derived.
