摘要
利用特定的振动与噪声测试和分析系统,采用实验模态分析与软件模态分析相结合的技术手段,对1kW水平轴风力机桨叶的结构动力特性进行了系统研究,为风力机桨叶的进一步优化设计和整机向大型化发展提供了重要的科学依据和实践经验。
Studying on the structure＇s dynamical characteristic of rotor blade of the horizontal-axis-wind-turbine is an important basis to analyze stability and reliability of wind turbine＇s, also is an important work for designing the rotor blade. Adopting the conjuncts of experimental mode analysis and software mode analysis, the rotor blade structure＇s dynamical characteristic of an-1kW- horizontal-axis-wind-turbine was analyzed with specific vibration, noise test and analytical system. It also can offer important scientific basis and practical experience to further optimization design of rotor blade and for the development of large wind turbine.
