风电叶片疲劳加载装置关键参数研究

Study on the Key Parameters of Wind Blade Fatigue Loading Device

风电叶片疲劳加载试验是指在试验室环境下用特定的装置模拟风载对叶片的振动疲劳作用,以此来检验叶片的疲劳寿命。该文以旋转偏心质量块共振(摆锤共振)加载装置为研究对象,介绍加载系统组成、工作原理以及试验步骤,使用共振能量分析的方法研究加载系统中各参数之间的关系以及参数的确定。

Wind turbine blade fatigue loading test is to obtain the blade fatigue life by simulating the fatigue effect of the wind load on the wind turbine in laboratory environment with specific device. This paper proposes rotating eccentric mass resonance （pendulum resonance） device as research object, introduces the composition, working principle and test procedure of the system, and uses resonance energy analysis method to study the parameter relation and parameter determination of the loading system.
