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。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.
