Abstract
The behavior of cavitation bubbles derived from the cylinder liner vibration was observed by a high speed camera system (IMACON 790), and the numerical analysis as for their behavior was compared with experimental date. The variable were the cylinder liner vibration velocity and the distance from cylinder liner to plate, and the relation between water pressure fluctuation and the bubble behavior was made clear. And also the calculation was tried in regard to the maximum impact pressure when the bubble was broken.
