  • 摘要: 针对单路单室航空发动机喷油嘴的内锥角测量难题，采用基于锥光全息技术的Cono激光测头，设计了一台五轴坐标测量机作为测量平台，建立了该坐标测量机的测量数学模型.利用参数化建模的方法，给出了空间锥面的最小二乘参数化目标函数，借助L-M优化算法实现求解.实验结果表明，测量的重复误差为0.001 9°，标准差仅为0.000 9°.故本文所提对喷油嘴内锥角的测量方法是可行的.
    Abstract: Aiming at solving the testing problem on the inner-cone angle of single-route and single-room aero-engine nozzle, a five-axis coordinate measuring machine was designed as the experimental platform using the Cono laser probe based on conoscopic holographic technology, followed by establishing its mathematical measurement model. The least squares parameterized objective function of the space cone was given and solved by means of L-M optimization algorithm. Experimental results showed that the testing repeatability was 0.001 9�, and the standard deviation was 0.000 9�. The proposed measuring method of inner-cone angle was feasible.
