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。 The main research is a kind of articulated wave energy device which consists of two parts: water surface floating body and underwater floating body. Due to its complex shape, Hydrostar software based on three-dimensional element method is used to calculate the hydrodynamic coefficients and wave excitation force of wave energy device. Mechanical analysis of the articulated wave energy device is performed. Finally, by choosing proper spring elastic coefficient and external damping coefficient, the relative moving amplitude of the optimized floating body and underwater floating body and the capture width ratio of the device can be obtained.
