喷管座粘接层的超声检测

Ultrasonic Detection for Bonding Layer of Nozzle Bracket

针对金属/橡胶胶结结构的结构特点及其材料的声学特征,介绍了该结构胶结质量的超声检测方法。以喷管座的粘结层的检测为例,重点介绍了如何利用超声多次反射法来检测脱粘缺陷,并通过试块制作和灵敏度调节等方法获得缺陷显示。试验证明,超声多次反射法可为其它薄壁复合件、橡胶复合材料件的常规检测提供借鉴和参考。

According to the structure characteristics of metal/cemented structure of rubber and material characteristics,the ultrasonic detection methods of the cement bond quality structure are introduced.The multiple reflection method,sample making,sensitivity adjustment and display discrimination are also introduced.Among them,some methods and measures are to target some special cases,such as ultrasonic multiple reflection method and block design.Present method can provide reference for conventional detection methods of other thin-walled composite and rubber composites.
