摘要
针对Spar平台垂荡-横摇-纵摇三自由度非线性耦合运动模型,在垂荡、横摇和纵摇固有频率接近2∶1∶1时的非线性耦合运动现象进行试验研究。采用1∶120制作模型,在规则波中测量不同波浪周期和波高下的非线性耦合运动响应。试验得到了平台固有运动特性,幅频响应特性,以及组合共振和内共振等非线性耦合运动规律,揭示了能量在垂荡、横摇和纵摇模态的渗透机理以及初始条件对能量在各模态转移的影响,确定了Spar平台发生组合共振和内共振的不稳定参数区域。为今后Spar平台的设计和运动预报提供了试验参考。
        The objective of this study is to investigate three-degree-of-freedom nonlinear coupling motion response of spar platform in a heave-roll-pitch mode by an experimental approach. The model test was carried out to study the nonlinear coupling motion when heave,roll,and pitch frequencies are approximately in a ratio of 2 ∶ 1 ∶ 1. A scaled model with a scale ratio of 1/120 was fabricated,and the nonlinear coupling responses of spar platform in regular waves with different wave periods and wave heights were measured. Through the model test,the natural characteristics of platform,amplitude-frequency response,as well as the nonlinear coupling motion phenomena such as combination resonance and internal resonance were obtained; this revealed the mechanism of energy penetration in heave,roll,and pitch,as well as the effect of initial condition on the energy transportation in different modes; moreover,the unsteady region of parameters which can excite combination resonance and internal resonance response was ascertained. This study can serve as a reference for the design and movement prediction of spar platform.
