针对等直径转轴动态扭矩测试方法计算模型和测量装置复杂以及测试范围受限等问题，提出了一种基于DASP的光电反射式动态扭矩测试方法。建立由光电反射式传感器和DASP系统等组成的动态扭矩测试系统，利用传感器光电脉冲信号的时差和相对转角，来实现动态扭矩测量。实测结果表明，通过调整传感器的位置，就可以实时、精确地实现扭矩的非接触式测量。这种测试方法为转轴的扭矩测试提供了一种新的技术途径。

Aiming at the problems of complex computation model, complex measurement equipment and test range limitation in dynamic torque testing of uniform-diameter rotating shafts, a dynamic torque testing method based on DASP and photoelectric reflex sensors was proposed. A dynamic torque testing system including photoelectric reflex sensors and dynamic data information collection equipment was established. Using the time difference of photoelectric sensor’s pulse signal and the relative angle, the dynamic torques could be measured. Experimental results show that real-time and accurate non-contact measurement of the dynamic torques can be realized through adjusting the sensor’s positions. This technology has provided a new method to test the dynamic torques of rotating shafts. This method is applicable to all kinds of large shaft dynamic torque measurements.
