Abstract: This paper presents a new array-type device of wave energy generation and describes its working
principle.A simulation model for this device was developed and its parameters and finite element mesh were
calculated by the method of AQWA. Using this model, we analyzed the RAO parameters of frequency
responses for a single float of different sizes and drafts and the characteristics of whole float array under
different angles of wave incidence. The results show that for a single float, when its draft is in the range
1.2-1.4m and its diameter 2.8m, the RAO parameter is maximized. And for the float array, a greater average
amplitude of relatively higher efficiency in capture of wave energy can be achieved at an incidence angle of
22.5° with a small variation in the amplitudes of different floats.
