Abstract航空機の整備コスト削減および運航の効率化に寄与する新たな非破壊検査技術の開発が求められている.本書は有望なNDIの新技術の1つであるLamb波を用いた超音波非破壊検査技術についてJAXAが実験を行った結果を示すものである.本実験では,AEセンサーを加振源として用い,Lamb波をアルミ平板中に伝播させることにより,Lamb波の伝播特性の調査および非破壊検査技術としての損傷検知/同定技術の可能性について検討した.平板中を伝播するLamb波の検出は,JAXAが保有する多軸振動非接触自動計測システムMaVES (Multi-axis Vibration Evaluating System) を用いて計測を行った.
The new Non Destructive Inspection (NDI) technology for aircraft has been required to reduce maintenance cost and to increase efficiency for aircraft operation. This document shows the experimental result obtained by ultrasonic Non Destructive test using Lamb wave which is one of the promising new NDI technologies. In this experiment, we used Acoustic Emission (AE) Sensor as the vibration source to propagate Lamb wave into the flat Aluminum panels. We investigate the propagation characteristic of Lamb wave and examine the capability of this method about the damage detection and identification for damages as NDI technology. The Multi-axis Vibration Evaluating System (MaVES) which JAXA developed is used to detect the Lamb waves in Aluminum panels.
