摘要
基于近些年有限元软件的优化与流行,在多体动力学的基础上,利用ANSYS workbench软件对大型风力机叶片进行的预应力模态分析。叶片是风力机获取动力的重要部件,对其合理的设计及有效地预防发生疲劳损坏有着重要的研究意义。本文是在满足工作环境下的3MW水平轴式风力机叶片的基础上,利用三维软件完成建模;并利用网格划分软件和流体软件在获取叶片上的气动压力的情况下,在workbench中进行的预应力模态分析,计算出叶片在各种应力下的各阶振型,分析结果并找出容易发生失效的的部位,进行预防和避开共振频率,防止破坏的发生。
.Based on the optimization of finite element software and popular in recent years, on the basis of multi-body dynamics, using ANSYS workbench software for large wind turbine blades of prestressed modal analysis.Leaf blade is an important part of a wind turbine for power, for its reasonable design and effectively prevent fatigue damage has important research significance.This article is in the work environment of 3 mw horizontal shaft type wind turbine blades, on the basis of using three-dimensional modeling software to complete;And use the grid software and fluid in the case of obtaining the pneumatic pressure on the blade, in the workbench prestressed modal analysis, calculate the vibration mode of the blade under various stress, the results of the analysis and find out the prone to failure parts, to prevent and avoid the resonance frequency, prevent the happening of the damage.
