摘　　要：传统双稳态波能装置已被证实在规则波中可以通过添加“自适应”特性,来解决由阱内振荡引起的低能量吸收问题。本文以自适应双稳态浮子式波浪能发电装置为研究对象,探讨装置在不规则波中的能量捕获性能情况。通过四阶龙格库塔法数值求解装置的运动控制方程,探究在不同装置参数下,自适应双稳态浮子式波浪能发电装置和传统双稳态浮子式波浪能发电装置以及线性浮子式波浪能发电装置的能量捕获性能表现。结果表明,选取适当的装置参数可以使自适应双稳态浮子式波浪能发电装置显著提升能量捕获性能,而且与线性和常规双稳装置相比,更适应于实际海况中波浪能量捕获。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 pow⁃er capture performance of an adaptive bistable float wave energy converter(WEC)in irregular waves was stud⁃ied.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.
