| 摘 要： | 针对柔性接头粘接检测存在的难点,分析了柔性接头部件的超声纵波传播规律及超声检测的“61o”现象,采用纵波直探头分析方法,有效地解决了构件厚度不均匀和钢层厚的难点。以回波峰值作为特征量,通过扫描成像来判断一、二界面的粘接状态。试验表明,此法检测精确度较高,达到检测要求。

| Abstract: | Aiming at difficult problems in the bonding detection of flexible joint,the propagation law of ultrasonic longitudinal wave and the 61~o phenomenon of the ultrasonic detection were analyzed.By using longitudinal wave straight-beam probe analysis method,some problems such as non-homogeneity and thichness were solved efficiently.Taking peak value of the wave as characteristic variables,bonding state between 1 and 2 interface was judged by scanning image method.The experimental results show that the method is of high precision and can meet detection demand. |
