Recently, the number of aged traffic structures is increasing in Japan. Most of them require constant maintenance to prevent an accident. Kobe city has a lot of aged illumination pillars and had two fall accidents, unfortunately. To detect an illumination pillar with a defect quickly, we apply a guided wave excited by electromagnetic acoustic transducers to a nondestructive testing system. This method has the potential for low-cost and efficient testing. When testing buried illumination pillars, it is neces...

Attenuation of Guided Wave by Buried Part on Nondestructive Testing of Illumination Pillar

This report is concerned with construction of an inspection robot system. The system is assumed to be composed of a set of nondestructive inspection devices and an autonomous moving robot. The inspection devices are assumed to be set over the target materials used in remote large artifacts while the robot is expected to acquire test data and to supply sufficient energies. This report is devoted to development of inspection device using electromagnetic acoustic transducer (EMAT). Guided wave inspection enabl...
