摘要
海洋平台的振动按其分布范围可分为总体振动和局部振动 ;按受力情况可分为自由振动和强迫振动。海洋平台是一类低频结构物 ,振动测试中所需要的主要是低频振动测试仪器。对测试方法和步骤进行了探讨 ,并对数据处理中应该注意的问题做了分析。
The types of vilration of offshore platforms were presented in this paper,which is classified into whole and local vibrations according to vibration range.They can also be classified into free vibration and forced vibration.As far as the vibrancy frequency of offshore platform is concerned,offshore platform is regarded as a low frequency structure.Then some of main measurement and instrument of vibration and some of questions about measurement and data processing are introduced and analyzed.
