摘要
介绍了水下拖缆隔振段隔振性能的测试装置和试验方法;分析了测试系统中隔振段两端串联弹簧对隔振性能的影响,隔振段的固有特性,不同拉力与激振量情况下的隔振效果以及轴向与横向的隔振性能。这些试验数据和分析结果,为线列声纳阵水下拖缆隔振段的设计提供了技术依据。
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.
