| 摘 要： | 将深水铰接塔平台顶部工作单元简化为集中质量,塔柱和浮力仓简化为均匀直杆,建立了铰接塔平台运动分析模型。考虑海流和波浪对平台的作用,应用Morison公式计算铰接塔平台瞬时位置所受水动力,依据拉格朗日原理建立了铰接塔平台的强非线性时变系数两自由度运动控制方程。文中工作为深水铰接塔平台动力响应分析奠定了基础。 |
| 关 键 词： | 铰接塔平台 波流联合 动力学模型 非线性方程 时变系数 |

| Abstract: | The units on the top of articulated tower platform(ATP) is simplified into one concentrated mass.Tower and buoyancy cabinet are simplified into uniform rigid bar.The model for ATP is put forward for dynamics analysis.Considering current and wave loads,the hydrodynamic force is evaluated at the instantaneous position for the ATP by Morison formula,the highly nonlinear time varying coefficient motion equation of two freedom degrees is established by Lagrange principle,which lays down the foundation for analys... |
| Keywords: | articulated tower platform combined wave-current dynamics model nonlinear equation time varying coefficient |
