埋込金物に対するAEセンサを用いた打音検査の効率化に 向けた取組み２
概要
Non-destructive evaluation technique was developed to identify the integrity of embedded hardware using digital hammering inspection with AE (Acoustic Emission) sensor. The inspection can diagnose the fixed state of the embedded hardware in terms of its natural frequency and vibration duration. Mockup tests were conducted to investigate the relationship between the change in vibration duration and the fixed state under various loads including external tensile loads and thermal loads when welding supports on the hardware.
