摘　　要：波浪激励下内置式波浪能发电装置的能量转换机理尚不清晰,影响了能量输出效率和稳定性。基于势流理论、莫里森方程和拉格朗日-欧拉方程,建立内置偏心摆式波浪能发电装置的三自由度动力学模型,并通过对比理论计算数据与水池试验数据,验证了模型的有效性。基于所建立的动力学模型,分析波浪激励条件、阻尼系数、偏心摆质量及偏心摆安装高度对装置运动响应的影响,并进一步研究能量转换过程的混沌效应,明晰装置混沌状态与输出功率之间的关系,揭示能量转换机理。The energy conversion mechanisms of the inner eccentric pendulum wave energy converter under wave excitation is still unclear,thereby impacting the converter’s output efficiency and stability.Utilizing the principles of potential flow theory,the Morrison equation,and the Lagrange-Euler equation,this study establishes a three-degree-of-freedom dynamic model for the inner eccentric pendulum wave energy converter.The validity of the model is verified by comparing the theoretical calculation data with the experimental data of the pool.Based on the established dynamic model,the effects of wave excitation condition,damping coefficient,mass of eccentric pendulum and installation height of eccentric pendulum on the motion response of the device are analyzed.Additionally,a comprehensive analysis is performed to explore the chaotic behavior in the energy conversion process.This research clarifies the relationship between the chaotic state of the device and the output power,and reveals the energy conversion mechanism.
