中文摘要：

主要研究包含水面浮体和水下浮体两部分的一种铰接式波能装置。由于其外形较复杂，为了计算得到波能装置的水动力学系数和波浪激励力，采用基于三维面元法的Hydrostar软件进行水动力学计算。对铰接式波能装置进行受力分析得到装置的力学方程。最后通过适当选取弹簧弹性系数和外部阻尼系数，可求得优化的水面浮体和水下浮体的相对运动幅度以及装置的俘获宽度比。

英文摘要：

A kind of hinged wave energy device with a floating body and a submerged body was studied. In order to get the hydrodynamic coefficient and wave excitation force of the device with complicated shape, the software HydroStar based on 3-D surface element method was used. The motion equations were established when force analysis was carried out for the hinged wave energy device. By selecting appropriate spring stiffness coefficient and external damping coefficient, the relative motion between the floating body could be obtained. and submerged body, and the capture width ratio of the device
