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
