Abstract
To improve the utilization efficiency of offshore wave energy,a dual stroke wave energy generation device based on a ratchet type ocean wave energy generation device is designed to achieve effective power generation in both upper and lower strokes.The device mainly consists of a float,reciprocating parts,gear mechanism,and two ratchet mechanisms.The float moves up and down to drive the rack to reciprocate,and the ratchet mechanism drives the transmission shaft to rotate through mechanical transformation,converting wave energy into unidirectional mechanical energy for power generation.Using ANSYS finite element software for static analysis of ratchet and pawl,material properties are determined,mesh is divided,and constraints and loads are applied.The results show that their stiffness and strength meet the design requirements.For example,the maximum deformation of ratchet is 0.004 5 mm and the maximum stress is 10.62 MPa,while the maximum deformation of pawl is 0.005 8 mm and the maximum stress is 11.27 MPa,all of which are far below the yield strength of the material.Using AQWA software to conduct hydrodynamic simulation analysis on the energy harvesting structure float,determining the size and mass parameters of the float based on simulated environmental parameters,and ensuring that the wave excitation force can provide sufficient driving force.The overall performance of the device is reliable,effectively improving the efficiency of wave energy utilization.关键词
