摘　　要：以水平参数摆波能装置为研究对象,通过物理模型试验、数值模拟和强迫激励模型,对装置多自由度下的运动和获能规律进行研究。装置在系泊状态下多自由度运动平均功率出现两个峰值,第一峰值与外浮体自身性质有关,第二峰值受系泊影响。将动力输出装置(PTO)阻尼形式、外浮体形状、系泊系统为变量,研究表明在斋堂岛海域,线性阻尼性能优于常值阻尼;外浮体为半球形和半圆柱形时装置获能较好;系泊轴向刚度、线密度对获能第二峰值的影响显著。A horizontal parametric pendulum wave energy converter is used as a research object to study the motion and energy acquisition law of the device under multiple degrees of freedom through model test,numerical simulation and prescribed excitation model.The average power of the device in the moored state with multiple degrees of freedom motion appears two peaks.The first peak is related to the nature of the outer float itself and the second peak is affected by the mooring.In this paper,taking the PTO damping form,the shape of the outer floater,and the mooring system as the research variables,and the study shows that the linear damping performance is better than the constant value damping in the sea area of Zhaitang Island.when the outer flouting body is hemispherical or hemispherical,the device obtains better performance.The influence of mooring axial stiffness and linear density on the second peak of energy acquisition is significant.
