摘　　要：为研究双螺旋旋耕埋草刀辊工作性能,基于虚拟仪器技术开展了埋草刀辊主轴转矩转速检测系统研究。利用JN338A型旋转式扭矩传感器和Nl PCI—6024E同步采集卡,在LabVIEW 8.6环境下设计了一套旋耕埋草刀辊主轴转矩转速检测系统。为研究刀辊运动参数与工作转矩间的规律,运用该检测系统进行了室内土槽试验研究。分析结果表明,刀辊工作时的前进速度和耕作深度对工作扭矩有显著影响。In order to research the working performance of the and Stubble-mulch knife-roller,the method of torque measurement which based on virtual instrument technology was carried out and researched.A measuring system of torque and rotor speed which was made up of JN338A rotational sensor and Nl PCI—6024E and LabVIEW 8.6 was designed.The soil-bin experiment with the measuring system was carried out to find the relationship between the knife-roller’s motion parameters and torque.The results show that the forward speed and embedded depth have evident influence on torque.
