摘要
为了缩短风电叶片疲劳测试周期,提出了一种基于电驱动的两轴共振疲劳加载方法。给出了两加载源速度和相位的检测方法,并以此制定了同步控制策略。整个控制系统采用主从式两级网络构架模式,采用高速脉冲计数传感器测量2个加载源的速度和相位,采用激光测距仪测量叶片振幅,并采用Labview软件开发了上位机监控界面。试验结果表明,该监控系统能很好地测量加载源的转速、相位和叶片振幅等特征参数。
In order to shorten fatigue test period of wind turbine blades,a fatigue loading method based on the dual-axes resonance driven by electricity is proposed.The method for detecting the speed and phase of the two loading sources is given,and the synchronization control strategy is formulated.The master-slave network framework mode is applied in the control system.The speed and phase of the two loading sources are measured by using high-speed pulse counting sensor,the blade amplitude is obtained by laser range finder,and the PC monitoring interface is developed by using Labview.Test results show that the speed,phase,blade amplitude of the loading sources and other characteristic parameters can be measured well by using the monitoring system,which provides a new test platform for dual-axis resonance fatigue test of wind turbine blades.
