摘要: 针对现有的四轴平动扫描成像系统检测航空转子时系统定位精度低、抗干扰能力差的问题，研制了一套五轴超声成像检测系统。该系统对检测工作台，探头夹持装置及抗干扰装置进行了优化设计，改进了滤波方式，并在软件中加入探头对中算法。采用该系统进行抗干扰性试验，并对系统的定位精度进行验证，试验结果表明，五轴超声成像检测系统的定位精度高，成像效果好，能有效抑制电磁干扰，实现转子的连续稳定检测。Abstract: Aiming at the problems of low positioning accuracy and poor anti-interference ability of the existing four-axis translational scanning imaging system for detecting aeronautical rotors, a five-axis ultrasonic imaging detection system was developed. The system optimizes the design of the detection workbench, the probe clamping device and the anti-interference device, improves the filtering method, and adds the probe alignment algorithm into the software. The system is used for anti-interference testing, and the positioning accuracy of the system is verified.The experimental results show that the five-axis ultrasonic imaging detection system has high positioning accuracy, good imaging effect, can effectively suppress electromagnetic interference, and realize the continuous and stable detection of the rotor.
