Abstract

Research Object

Taking the acquisition mechanism of oscillatory flapping-wing wave energy as the research object, the scheme design and dynamic analysis of the acquisition mechanism are studied.

Research Methods

According to the working principle of the acquisition mechanism of oscillatory flapping-wing wave energy, the rotation dynamics model of the acquisition mechanism and the corresponding relationship between the model parameters and the design parameters of the mechanism are established. Based on the momentum moment theorem, the differential equation of the dynamics of the acquisition mechanism and the transfer function of the system are established. The dynamic response of the acquisition mechanism is analyzed, the system parameters are optimized, and the scheme design is carried out. The conversion efficiency of the acquisition mechanism and the energy collection efficiency under different sea conditions are calculated. The motion response of the acquisition mechanism is simulated and analyzed by MATLAB and AQWA software.

Research Results

The results show that the response of the crank and swing slider acquisition mechanism is fast and stable, and the average conversion efficiency is 34%. The research process provides an effective reference for the development of the acquisition mechanism of oscillatory flapping-wing wave energy.
