Thermal Wave Technique Inspection of Debond Defect for Solid Missile Motor

  • 摘要: 针对固体导弹发动机常见的金属壳体与绝热层脱粘缺陷, 利用热波技术进行了检测研究。借助于数值分析方法, 研究了热波探伤技术的检测过程, 并深入研究了缺陷直径对检测灵敏度的影响, 最后进行了试验验证。仿真及试验结果均表明: 热波技术对绝热层脱粘缺陷检测速度很快, 能够实现对缺陷的准确定位和定量检测; 并且缺陷直径越大, 越容易检测。试验中还发现了未知缺陷, 经分析判断可能是由于制造工艺原因导致的粘接界面出现了不均匀结构, 表明热波技术还能够对粘接界面的质量进行检测和评估。
    Abstract: Thermal wave technique(TWT) has gained broad application attributed to the advantages of such as high speed, non-contact and can achieving on-line inspection capability, etc. In this paper, TWT was used to detect the disbond defect between shell and heat-insulating layer of Solid Missile Motor(SMM) for nondestructive inspection. Numerical simulation method was used to investigate the process of TWT and the effect of defect size on the testing sensitivity was further studied, which was verified by experiment. The results of the simulation and experiment show that the TWT has a high speed of detecting the disbond defect, which could ascertain the defect position exactly and achieve quantitative testing for the defects. Moreover, the bigger of the defect, the easier be detected. An un-known defect may be caused by manufacture techniques was found out by the experiment, which indicated that thermal wave technique could also inspect and evaluate the quality of adhesive interface.
