摘要：

In previous papers, the authors proposed the fixed type and floating type wave energy conversion systems using ball screws. The fixed type is composed of a pressure plate and a ball screw type turbine settled in a caisson, and the floating type is composed of a floating body and one or two wave power buoys with a ball screw type turbine. The ball screw type turbine consists of a ball screw, a one-way clutch, a flywheel and a generator. The ball screw is useful in transforming slow linear motion into fast rotary motion with a high efficiency of more than 90%, and wave power is efficiently converted into electric power by the ball screw. In this paper, the output characteristics of the fixed type and floating type wave energy conversion systems using the ball screw type turbine are calculated and compared. Both types of experimental models were made, and tank tests were carried out. The experimental results were compared with the calculated results, and the output characteristics and the propriety of the calculations were substantiated.
