摘    要:应用线性波理论与Morison方程,计算出漂浮式海浪发电装置主浮体在极端海浪条件下受到的海浪冲击力。利用三维软件建立海浪发电装置及其主浮体模型。利用ANSYS Workbench软件与三维软件的接口,建立主浮体的有限元模型,求解其在海浪冲击作用力下的位移及应力响应。仿真结果表明:主浮体在极端风浪的冲击作用下,应力响应与位移响应均在振型处达到最大值,但处于所规定的安全范围之内。

关 键 词:海浪发电  模态分析  动力学  Morison方程

Abstract:In order to assess the security of the floating wave power generating device,the wave impact force on the primary floating body in extremely arduous condition was calculated.The linear wave theory and Morison equation were employed in the calculation.The finite element model for the wave-power generating device was established by adopting ANSYS software.During the simulation process,interface was utilized to convert the three-dimensional model to Workbench model.The displacement variety and harmonic driving response of the primary floating body with the wave impact force were obtained.The simulation results showed that the stress and displacement variety both reached their maximum values under the impact of the extreme wind and waves,while all within the required security range.
Keywords:wave power generation  model analysis  dynamics  Morison equation
