Conventional bistable wave energy devices have been demonstrated in regular waves by adding adaptive properties to solve the problem of low energy absorption caused by the intrawell oscillation.The power capture performance of an adaptive bistable float wave energy converter (WEC) in irregular waves was studied.The motion equations were established and solved numerically by the fourth-order Runge-Kutta method. The power capture performance of adaptive bistable WEC, conventional bistable WEC and linear WEC was investigated under different device parameters. The results show that with proper device parameters, the adaptive bistable WEC can significantly improve the energy capture performance, and is more suitable for wave energy capture in actual sea conditions than linear and conventional bistable devices.
