Aim\ Study on new methods of the detection of adhesive quality between metalic and nonmetalic components. Methods\ It accomplishes nondestructive evaluation of mechanic properties by giving a little force to adhesive structure, by detecting microphone array and processing and recognizing of signals. Results and Conclusion\ A method of acoustic excitation for detecting adhesive quality interface of metal and nonmetal, and some problems, such as, coupling difficulty of ultrasound detection, slow detecting rate, low detecting sensitivity and high misjudged rate, have been solved partially.
