摘　　要：设计一种新型密封式波浪能俘获装置,浮体随波浪进行摆动,驱动浮体内摆体旋转,将波浪能转换成机械能;通过选取4种摆体的形状进行对比,选出最佳的摆体形状,并建构摆体的数学模型;利用Matlab软件对摆体在不同波浪条件下进行数值求解,之后在水动力测试平台进行模型试验。结果表明:球体是最佳的摆体形状,其装置俘获效率较高,且结构简单、成本较低,可为下一步定量优化装置提供有效的理论依据。A new sealed wave energy conversion device is designed in this paper.The floating body oscillates with the waves,drives the floating body to rotate,and converts wave energy into mechanical energy.By comparing the four shapes of the pendulum body,the best shape of the pendulum body is selected and the mathematical model of the pendulum body is constructed.Matlab software was used to solve the pendulum body numerically under different wave conditions.Then a model test was conducted on the hydrodynamic test platform.The results show that the optimal shape of the swing body is sphere,the device has high capture efficiency,simple structure and low cost,which provides an effective theoretical basis for the next quantitative optimization device.
