Abstract
This paper describes the results of the experimental study on the vibration characteristics of liquid bridge between a solid sphere and a flat solid plate subject to vertical vibration. Experiments were performed on a vibration-testing system. In this experiment, the sample liquid was water, the sample sphere was small aluminium oxide ball, and the sample solid base was the acrylic plastic plate. The dynamic behavior of the solid sphere-liquid bridge system was observed with a high-speed video camera system. It was found that the fundamental responses of the sphere were determined by the excitation acceleration. Capillary adhesion force produced by the surface tension of water was dominant at lower excitation accelerations. The vertical vibration led the sphere-liquid drop system to the chaotic motions at higher excitation accelerations.
