摘要

FIELD: machine building.;SUBSTANCE: invention relates to vibration equipment and can be used in various industries. Method of the amplitude controlling during the automatic tuning to the driven by induction motor vibrating machine vibrations resonance mode is that vibrating machine with a damper with predetermined dissipative characteristics working body vibrations are excited by periodic force due the driven by the induction motor inertial vibrations exciter unbalance rotation, whose rotational frequency is adjusted to the vibrating machine mechanical system oscillations resonant mode by the predetermined algorithm, for which purpose simultaneously measuring the working member movement and the unbalance angular position. Then, measuring the working member vibrations amplitude mismatch with its preset value, changed the energy dissipation value in the damper, reducing the working member vibrations amplitude mismatch to zero, at that, the dissipation value change is calculated by the given algorithm, which connects the working member vibrations amplitude and the damper dissipative characteristics.;EFFECT: technical result consists in the required amplitude maintaining with automatic adjustment to the vibrating machine working member vibrations resonance mode.;1 cl, 1 dwg
