摘　　要：在机械构件的应变检测中,传统的应变片法由于需接触检测而难以满足检测要求。基于电磁检测原理提出了受扭构件切应变的非接触实时在线定量检测方法,设计了以AT89C52为核心的旋转构件切应变检测系统。介绍该系统的功能、硬件构成、软件设计及其实现。仿真试验表明,该系统运行可靠,检测准确,具有推广应用价值。Conventional strain-gauge method can not satisfy the measurement of the strain of mechanical component for its contacting pattern. Non-contact real-time on-line quantitative testing of the shear strain of the component twisted based on electromagnetic testing was put forward. AT89C52 based and angular strain testing system was designed. The system function, hardware structure and software design were also given. Simulation experiment showed that the system could provide reliable and accurate testing and was valuable for practical application.
