Evaluation of the Double Snap-Through Mechanism on the Wave Energy Converter’s Performance

چکیده
Abstract Lower efficiencies induce higher energy costs and pose a barrier to wave devices’ commercial applications. Therefore, the efficiency enhancement of converters has received much attention in recent decades. The reported research presents double snap-through mechanism applied hemispheric point absorber type converter (WEC) improve absorption performance. comprises four oblique springs mounted an X-configuration. This provides WEC with different dynamic stability behaviors depending on particular geometric physical parameters employed. these (linear, bistable, tristable) was initially evaluated under action regular waves. results for bistable or tristable responses indicated significant improvements WEC’s capture efficiency. Furthermore, frequency bandwidth shown be significantly enlarged when mode operation. However, corresponding trajectory showed intra-well behavior middle potential well, which induced more severe low-energy small amplitude acted compared Nevertheless, positive effects were observed appropriate initial conditions imposed. also that responses, suitable spring stiffness may cause buoy oscillate high modes.
