摘要
为了研究摆锤杠杆式海浪发电装置摆锤杠杆结构安全性能,根据微幅波理论与弗汝德-克雷洛夫假设,计算出摆锤杠杆式海浪发电装置摆锤杠杆在一定波高条件下受到的海浪波浪力,利用Solid Works三维软件建立海浪发电装置主体结构及其摆锤杠杆模型,对摆锤杠杆结构进行静力学分析,把固定结构及整个发电装置结构三维模型分别导入到ANSYS worksbench中进行模态分析,求解出其在海浪冲击作用力下的位移及应力响应。结果表明:摆锤杠杆在一定波高的作用下,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,能够满足发电要求。
In order to study the safety performance of the pendulum lever structure of the pendulum lever type wave power plant,based on the theory of micro amplitude wave and the assumption of Froude,the wave forces on the pendulum lever of a pendulum lever type wave power generation device under certain wave height were calculated. SolidWorks 3D software was used to build the main structure and pendulum lever model of wave power generation device. Static analysis of the pendulum lever structure was conducted. The model analysis of the fixed structure and the three dimensional model of the whole power plant structure were introduced into ANSYS worksbench. The displacement and stress response of the wave under the wave impact force were solved. The analysis results show that the stress response and displacement response of the pendulum lever reach the maximum value at the vibration mode under certain wave height,but within the specified safety range,they can meet the power generation requirements.
