resonance

The purpose of research: development of method of optimization of the resonance vibro-impact system stiffness parameters with technological limitations of kinematic and dynamic characteristics. The synthesis is based on a numerical dynamic analysis which uses methods of tackling nonlinear differential system of equations. The discrete algorithm of choice-based optimization of synthesized coefficients of asymmetric lump linear stiffness characteristic with limitations imposed on technological parameters and system frequency characteristics is proposed.

The influence of internal friction parameters in the joints of structural elements on the machine for vibration amplitude of cutting tool and detail was analyzed. The possibility of effectively suppress the amplitude of oscillation of the cutting tool by selecting optimal parameters of frictional connection of the cutting blade was shown.
