FIELD: machine building.
SUBSTANCE: dampers are subjected to vibration tests at varying frequency and fixed frequency during several stages. Acceleration amplitudes, at every stage, are varied from minimum to operating values. Tests are effected at all stages with replacement of one of damping elements with inserts of the same structural design an density. Static and dynamic hysteresis curves are obtained and characteristics are compared. Additional test stages include sequential replacement of damping elements with inserts and stage-by-stage increase in the number of replaced damping elements. Proceeding from obtained results, amplitude-frequency range of damper efficient operation is selected.
EFFECT: higher accuracy.
