风力机叶片动力特性实验台设计

设计开发了一种风力机叶片动力学特性实验台,可以进行风力机叶片的静载荷实验、模态测试、叶片损伤测试、模拟桨叶结冰附着物载荷实验、桨叶疲劳载荷实验以及破坏性实验等。介绍了实验台的设备组成、结构特点以及该实验台的主要功能,在实验台上进行了风力机叶片的静态载荷实验和模态测试,得出了实验用风力机叶片的六阶模态参数,利用MAC、MOV两种模态判定准则对试验结果进行了验证。

Design of a Test Rig for Testing the Power Characteristics of a Wind Turbine

Designed and developed was a wind turbine blade dynamic characteristics testrig,on which a wind turbine blade static load test,mode test,blade testing,blade non-destructive inspection,propeller and blade icing attached substance load simulation test,propeller and blade fatigue load test and destructive testsetc.can be performed.On this basis,the composition of the equipment items,structural features and the main functions of the test rig were described.On the test rig,a static load and mode test of a wind turbine blade were conducted and a 6-order mode parameter of the wind turbine blade was obtained.The MAC and MOV two mode criteria were used to verify the test results.
