Impact sound testing machine and impact sound testing system

Abstract

The present invention provides a sound-based inspection machine that allows for easy and consistent impact on the inspection surface, enabling highly accurate evaluation of the deterioration state of structures. [Solution] The impact sound inspection machine comprises an inspection machine body that moves along the inspection surface of a structure, an impact device provided on the inspection machine body that strikes the inspection surface, a sound collection device that collects the impact sound of the impact device, and a movement assist device that moves the inspection machine body parallel to the inspection surface. The impact device comprises an impact rod that rotates along the inspection surface in a circular trajectory with a rotation axis perpendicular to the inspection surface and strikes the inspection surface, and a rotation drive unit that rotates the impact rod.

Claims
