摘　　要：介绍了作为隔振模块研究依据的拖缆抖动特性的试验研究结果及隔振模块理论分析方法 ,给出了隔振模块有关参数变化对隔振量影响的理论值 ,提供了隔振模块隔振量试验方法 ,某隔振模块隔振量的测量结果以及装与不装隔振模块情况下 。In the towed array sonar,vibration isolation modules(VIM) are incorporated both ahead and astern of acoustic modules to minimize vibration from stern array swing and tow cable shaking. In this paper, tow cable vibration characteristics essential for VIM research are obtained experimentally and VIM theoretical analysis methods are given along with theoretical values that indicate vibration isolation effects varying with VIM parameters. In addition, experimental methodology and experimental data for a sample VIM are provided and experimental towed noise spectra of acoustic modules both with and without VIM are compared.
