Dynamics of the vibration driven tool at its interaction with the processing material

摘要

This paper presents the investigation of the interaction dynamics between the vibrating tool and the technological load. The vibrating tool is equipped by the controllable debalance on the electric drive. Stationary and non-stationary movement regimes of the working body are analyzed. Qualitative and quantitative dependence between tool electromechanical parameters and its movement characteristics is established. Influence of technological loading on the frequency characteristic is revealed. On the basis of the analysis of transitive regimes of movement the optimal control law is offered.
