基于虚拟仪器的旋翼特性测试平台开发

摘要

To test the rotor characteristics , a simple platform of testing the speed , lift, torque of the rotor is designed.Using LabVIEW program to send PWM pulse to control electronic governor driving motor ,the rotor is rotated with motor .At the same time , data acquisition card is triggered for multi-channel synchronous data collection .Data acquisition card collects the signals of rotor characteristics transferred by the corresponding sensor .Through the LabVIEW ,data are read ,processed ,displayed and stored .The platform can obtain the data about speed,lift,and torque of the real-time rotor.The results confirm that the test platform can get accurate data about rotor features .%为测试旋翼特性，设计一个测试旋翼转速、升力、转矩的简易平台，运用LabVIEW程序发送PWM脉冲控制电子调速器驱动电机带动旋翼，同时触发数据采集卡进行多通道同步数据采集。通过数据采集卡采集由对应的传感器传输的旋翼特性信号，并通过LabVIEW对数据进行读取、处理、显示及存储。测试平台能够实时得到任一时刻旋翼转速、升力及转矩。测试结果表明，测试平台能够准确得到旋翼特性数据。
