光纤传感器在带传动参数测量中的应用

提出一种用光纤传感器测量高速旋转构件微小位移量的新方法，实现了非接触式高速、高精度的位移测量。在介绍光纤传感器测量原理的基础上，得出光强与测距之间关系式。将光强转为电压信号，建立电压商值与测距之间的拟合公式。设计V带参数测量实验台，对V带稳定运转时其在轮槽中的径向位移进行测定，进而得出V带在带轮中的轨迹，测量出滑动角的大小。针对原有V带滑动角计算公式中的不足进行优化，得出新的滑动角计算公式。对比实验结果，新公式更接近实验结果，误差更小，为V带的精确设计提供理论依据。

Application of optical fiber sensors in measurement of belt transmission parameters

A new method of using optical fiber sensors to measure tiny displacement of high-speed rotating component was proposed to realize the non-contact high speed and high precision displacement measurement. On the base of measurement principle of optical fiber sensors, relation between light intensive and range was calculated in this paper. Voltage fitting formula between business value and range was established by turning a light intensity into a voltage signal. Test bench for measuring the parameters of V belt was designed to measure the radial displacement of V belt when stable operating in race to get the knowledge of track of V belt in belt pulley and the slide angles. New sliding angle formula was drawn by continuous optimizing the original V belt sliding angle. Comparative results from two experiments show that the new formula is more accordance with experiment with less error and can provide theoretical basis for the accurate design for V belt.
