摘要
利用LabVIEW研制了风电叶片疲劳加载综合测试系统,包括数据采集显示、数据存储和通信控制等功能。采用激光传感器测距,虚拟仪器软件采集数据处理,PLC趋势二分法搜索频率,执行相关程序算法对频率跟踪、输出控制,完成叶片疲劳加载测试过程。试验结果表明:使用图形化软件编程,数据处理功能强大,操作简便,检测效率得到很大提高,降低了设备成本,为风电叶片检测与分析提供一种的实用手段。
A fatigue loading test system for wind turbine blade using virtual instrument software LabVIEW was developed suc- cessfully, including the function of data acquisition and display, data storage and communication control. The laser sensor was used to measure the distance, and the virtual instrument software was used to collect the data. The frequency was searched with PLC trend dichotomy. Frequency tracking and output control were realized by implementing related procedure algorithm, thus the fatigue test process was finished. The experimental results show that the system is powerful in data processing and simple to operate by using the graphical programming software, the detection efficiency is greatly improved and the equipment cost was reduced, thus providing a practical way for the test and analysis of wind turbine blade.
