船舶推进轴系横向振动模态试验研究

Modal Testing folr Horizontal Vibration of Ship Propulsion Shafting

本文针对船舶轴系试验台的轴系横向振动组织了3种方案的振动试验,并进行了轴系横振模态参数识别。通过分析比较,获得一组精度较高的模态参数,为进一步的动力学模型修正打下了基础。此外,还对振动试验及分析中应注意的问题进行了讨论。

Three sorts of experiments have been done for shafting's horizontal vibration on the test bed of ship shafting, modal parameters are identified with Klosterman's method. Following signal analysis and discussion on testing techniques, a set of accurate modal parameters are obtained and presented in this paper.
