Recently, the shock, noise, and erosion produced by collapse of cavitation bubbles have been a crucial problem in fluids engineering. It is known that severe cavitation also occurs in the surroundings of oscillating objects inside of still liquid as well as in high-speed liquid. Few studies, from hydrodynamical viewpoints, have been conducted on cavitation bubbles of vibratory apparatus such as the equipment of ASTM irrespective of its importance. Therefore, in this report, some experiments based on the vibratory apparatus in still liquid were photographically conducted in order to study the vibratory cavitation with high impulse. The main results are related to instantaneous pictures of collapsing bubbles and measurements of impulsive force at the collapse of bubbles.
