海洋固定平台结构的振动分析方法及算例

Structural Vibration Analysis Method and Calculation Example of Offshore Fixed Platforms

以渤海油气田某注气平台为例,介绍应用ANSYS有限元软件进行振动分析的方法和步骤,阐述结构振动模拟前提和评判准则,并给出结构减振建议,为海上固定平台振动分析提供借鉴。

Taking a gas injection platform in Bohai Bay gas field as an example,this paper introduces the methods and steps of using ANSYS software to perform vibration analysis.The premise and criteria of structural vibration simulation are elaborated.Some suggestions for structural vibration reduction are proposed,which provides a reference for the vibration analysis of offshore fixed platforms.
