导弹发射筒超声自动探伤系统设计

Design of Automatic Ultrasonic Flaw Detection System for Missile Launch Canister

发射筒是某型导弹发射车实施导弹发射的核心部件,对安全性具有很高的要求,每次发射后必须进行探伤检查。为提高探伤的效率和准确性,并使探伤结果的显示更加清晰直观,设计了一种具有三自由度超声扫描驱动装置的自动探伤系统,并在软件设计中提出了基于空域相关滤波的超声信号处理方法和探伤结果的B扫描成像方法。目前,该系统已在某型导弹发射设备的装备保障任务中得到了实际应用,并取得了良好的使用效果。

The launch canister is a core component of a type of missile launch vehicle, which requires flaw detection after each launch mission, to meet the high requirement of safety. To improve the efficiency and accuracy and to get a more vivid result display, the automatic flaw detection system equipped with three-degree-of-freedom ultrasonic scan drive device was designed. The ultrasonic signal processing method based on spatial correlation filtering and the flaw detecting result based on B-scan imaging method were also proposed in the system software design. The system has been used already in the maintenance missions of a type of missile launch equipment, and the good application effect is also shown.
