【摘要】 机舱在风力发电机中是一个很重要的受力部件,本文基于ANSYS有限元软件平台,通过对机舱进行静力分析和模态分析,得出了机舱应力分布图及最大应力值;机舱前5阶的固有频率及振型。根据最大应力出现的位置和机舱的振型,我们提出了优化方案,为风力机研究中虚拟设计方法的应用进行了一次有益的探索。更多还原

【Abstract】 In wind turbine the engine room is an important construction part.On the finite element software ANSYS the static and mode analysis for engine room is given. Including the stress distribution of it, the maximum stress, the natural frequency of the first 5 ranks and its vibration modes. According to the position of maximum stress and its vibration mode, the optimized suggestions is put for word. All of this shows a new way for the wind turbine research in its virtual design.更多还原
