| 摘 要： | 为准确测量直升机标准桨叶在动平衡试验中的挥舞参数,该文采用桨叶切割激光光路方法把位置参数转化为激光脉冲时序参数,实现桨叶挥舞参数的非接触测量.通过补偿算法降低桨叶挥舞角自身引起的非线性误差,利用测量装置本身的激光器和时序算法对测量系统的安装参数进行定位校准,用一组标准厚度的模拟桨叶标定桨叶挥舞参数测量装置.试验结果表明,测量系统的测量不确定度满足标准桨叶校准的技术要求.该方法实现了标准桨叶挥舞参数的测量,而且测量结果可溯源到几何量标准. |

| Abstract: | In order to measure the flapping track of standard rotor blade in dynamic balance test,a method which is based on curtaining off the laser bean by rotor blades to transform the position parameters into pulse-train analysis is proposed to measure the flapping height of standard blades with non-contacting measurement.The nonlinear error caused by flapping-angle is reduced by compensatory algorithm.The location-parameters of the measurement system can be calibrated with the lasers and pulse-train algorithm.The... |
