The radial and translational motion of spherical vapor bubbles in a cluster under the influence of ultrasound field of high amplitude (about 10 atmospheres) is studied. In mathematical describing of the problem the discrete model is used, according to which the dynamics of single bubble in a cluster is considered separately, and the interaction between bubbles is implemented by secondary Bjerknes forces. The possibility of amplification of radial pulsations of the bubbles by their joined motion is studied. The process of structure formation in a cluster and stability of oscillations (positional and radial) is investigated.
