| Abstract: | According to the model of the ultrasonic wave transmitting in the multi-layered media, this paper analyses the effect of the change of the multi-layered media’s thickness on sound pressure transmission rate and attenuation of the ultrasonic wave in the multi-layered media. And associated with the ultrasonic testing result of adhesion quality of steel-epoxy resin -Al adhesive structure, this paper also analyses the effect of the tiny change of the adhesive layer’s thickness on adhesion quality of multi-layered adhesive structure. It showed that the tiny change of the adhesive layer thickness produced great effect on the ultrasonic testing result. |
