| 摘 要： | Spar平台由于其优良的特性,近年来,在深水工程领域,得到了越来越广泛的应用.Spar平台由于其特有的几何特性,从而导致其在水流中可能产生涡激运动.文中针对Spar平台的刚体特性,建立了Spar平台与尾流振子之间的耦合运动方程,利用该方法对一模型平台进行了数值验证,计算得到的锁定区域与实验测得的结果吻合良好.接着对一真实的Spar平台进行了计算,并得到Spar平台和尾流振子的时间历程曲线.结果表明Spar平台的运动幅度以及运动周期比通常涡激振动的幅度以及周期要大.

| Abstract: | Spar platform has been employed more and more widespread in deepwater recently due to its excellent characteristics. The vortex induced Spar motions may be happened because of the special geometric characteristics of the structure. The coupled equations of Spar platform and wake oscillators are established according to the rigid characteristic of the Spar. A validation is carried on using the method for a model Spar platform,and the results show that the lock-in region using our method agrees with the exper... |
