【Abstract】 The test equipment and experiment method of vibration characteristics of VIM(Vibration Isolation Module) of the underwater cable are introduced. Also, the influence on capability of isolation vibration with and without springs in series at the start and the end of VIM in the test system is analyzed. In addition, the natural frequencies of the VIM, the capability of isolation vibration in the case of different values of pull and excitation, and the isolation vibration values in both axis and landscape orientation are investigated. The experimental data and analysis results provide a technologic basis to design VIM of the underwater cable in towed array sonar.更多还原
