| Abstract: | 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. |
