Abstract

The energy-force interactions in vibroimpact systems are studied according to the developed universal mathematical model, which simulates multi-mass vibroimpact systems, the masses of which are connected to each other and to a fixed base by nonretaining one-sided and retaining two-sided elastic bonds, with the excitation of these systems by inertial debalanced vibrators driven by a limited power The results of the research indicate a higher efficiency of vibrations of vibroimpact systems in comparison with a non-vibroimpact system of similar parameters. The highest energy efficiency of oscillations of vibroimpact systems and, accordingly, their maximum efficiency takes place at the excitation parameters that precede the disruption of vibroimpact oscillations. At the same time, maximum accelerations and reactions in their elastic bonds are excited in the systems. Based on this, it is necessary to accept the maximum permissible acceleration of the elements of their constructions as criteria for choosing rational process parameters in viboimpact systems, which ensures the reliability and durability of their operation.
