摘要：

针对传统浮子式波浪能采集装置无法将浮子转动动能转化为电能的问题，提出了一种张拉整体并联机构波浪能采集装置．基于线性波理论和拉格朗日方程，建立了张拉整体并联机构波浪能采集装置的动力学模型，分析了此装置的浮子在线性波浪作用下的位移和速度，对比研究了该装置和传统浮子式波浪能采集装置的能量采集效率．仿真结果表明，张拉整体并联机构波浪能采集装置比传统浮子式装置能量的采集效率高；另外，由于张拉整体并联机构波浪能采集装置中含有弹簧等储能元件，使得其抵抗极端波浪的能力较强．

Abstract:

To solve the problem that the conventional floating wave power device can not transform the rotational kinetic energy into electric energy, a novel wave energy harvesting device based on tensegrity parallel mechanisms is proposed. The dynamic model of the novel device is developed on the basis of Airy's linear wave theory and Lagrange's equation. Then, the kinematic and dynamic analyses of the float are made. Afterwards, the efficiency of the novel wave energy harvesting device and conventional floating wave power device is computed and compared. The results indicate that the efficiency of energy harvesting of the proposed device is higher than that of the conventional floating wave power device. Moreover, the ability of the proposed device to resist destructive water waves is better than that of the conventional floating wave power device.

Key words: tensegrity, linear wave theory, mechanisms, energy conversion, dynamic analysis
