摘要

    摘要
  • 摘要: 发动机转子叶片叶尖到开半机匣内壁径向距离是衡量发动机质量是否合格的一个重要指标，其值的大小对发动机的高效安全运行至关重要。利用立体视觉原理、自动聚焦技术和边缘检测算法，设计了一套发动机装配过程中叶尖间隙静态测量装置。该测量装置实现了对发动机叶尖间隙的非接触测量，且操作简单，测量精度高。实验结果表明该套装置测量精度达到20 m。
    Abstract: The gap from the engine rotor blade tip to the open half machine magazine is an important parameter that inspects whether the engine is qualified. And its value is of prime importance to the engine on high efficient and safe operation. Based on stereo vision principle, automatic focus technology, edge detection algorithm, this paper designed a blade tip clearance measurement device used in the process of engine assembling. This device realized the non-contact measurement to aero-engine rip clearance with simple operation and high-accuracy measurement. Experiment result shows that the device accuracy can reach to 20 m.
