| 摘 要： | 将造波水槽内二维浮体牵引弹簧回复液压缸的受力系统简化为弹簧—质量—阻尼器系统,建立数学模型,并根据牛顿第二定律得到运动方程式。采用基于简单格林函数的边界元方法对所研究浮体的水动力学系数和波浪力进行计算,对于施加给液压系统的不同外部阻尼值,由运动方程可得到相应的浮体垂荡运动位移。为求浮体对液压系统做功的最大值,在给定条件下着重对外部阻尼系数进行了优化。

| Abstract: | The model of a kind of wave energy device moored on seabed is simplified into a spring-mass-damping system,and then its motion equation is built according to Newton's second law.Boundary element method based on simple Green function is presented to analyze the vertical motion of the buoy that drives a hydraulic pressure device below.Optimal design of external-damping coefficient for attaining the maximum work produced by the buoy is discussed in detail.The result of the optimal design can be used to guide the practical work directly. |

| Keywords: | two-dimensional buoy boundary element method out-damping optimal design wave energy |
