摘　　要：应用虚拟仪器技术,对机械传动试验台进行了改造。扭矩测量使用JC型扭矩转速传感器,数据采集采用PCI-6024E数据采集卡,用LabVIEW语言编程,简化了测控系统,提高了测量精度,实现了对机械传动试验台信号进行数据采集、处理,并进行显示、存储、打印。研究采用不同的数据处理方法,对扭矩信号进行处理,得到了精度较高的数据处理方法。并对不同处理方法对精度的影响进行了分析。Virtual instrument is used to improve the functions of multi-functional transmission mechanical experiment set-up. JC torque sensor is used to measure torque, and the PCI -6024E data acquisition card is used to measure the data. By using LabVIEW language programming and simplifying the monitoring and control system to enhance the accuracy, Multi-functional Transmission Mechanical Experiment Set-up＇s signal data collection is realized in processing, and display, storage and printing. It uses different data-processing methods to process the torque signal, and obtains the higher precision＇s data processing methods. And the different treatment methods＇ of influencing the accuracy are analyzed.
