大跨度桥钢管桩的涡振研究
|
摘要
对在水流、波浪力作用下海洋独立支撑结构所产生的涡振进行非线性研究。该研究的目的是通过改变独立支撑结构自振频率来控制结构产生的涡振,以避免结构产生涡振破坏。提出涡振概念;分析独立支撑结构产生涡振条件、作用载荷、涡振频率以及振动方程的解。
The vortex vibration of offshore independence support structure under current and wave is studied by non-linear.The objective of the research was to control the vortex vibration was put forwarded.It analyzed many characters of independence support structure,including the condition of produce vortex vibration,the load,structure frequency and the solution of vibration equation
