Abstract:
Single-sided air-coupled ultrasonic inspection has some beneficial properties compared to water-coupled ultrasonic inspection or double-sided ultrasonic testing. The absence of the need for water leads to easier process handling on the one hand e.g. when manufacturing aircraft components. On the other hand, because the process is single-sided, reachability is a minor problem compared to double-sided testing and end-effectors and fixtures can be designed in a less complex and more compact way. However, the nature of lamb waves requires that the geometrical relation of the transmitter and the receiver varies during the inspection process. In this paper, a prototype of an adaptive end-effector is introduced that was developed to implement this requirement and results of first evaluation tests are presented.
