摘要
多截面分时测量叶片型面检测系统是针对发动机尺寸小、轴向弯曲度大的叶片型面检测而设计的。使用电感传感器触头接触叶身型面进行数据采集,采集到的数据通过RS232串口通信传输到计算机,由计算机进行数据分析,确定型面是否合格。该测量系统采用PCI-6221数据采集卡进行截面位置自动控制,判断当前截面号,调用此截面参数进行计算,仅以单个截面测量需要的10个传感器来实现整个型面n个截面的分时测量,大大节约了成本。使用LabVIEW的图形化软件编程,数据处理功能强大,操作简便,检测效率得到很大提高。
A time-sharing measurement system for multi-sectional of lamina is designed to solve the measure- ment problems of small size and large axial camber. Inductance sensor is connected to surface of lamina to ac- quire data which is transmitted to computer by RS232 and analyzed to determine eligibility. Numbers of current sectional are detected and selected corresponding parameter to calculate by using PCI-6221. The system is eco- nomical by using ten inductance sensors for one sectional measurement instead of more inductance sensors for n sectional. The system shows powerful data calculation and convenient operation with LabVIEW. Detecting efficiency is improved in practice.
