Purpose. Definition of influence static and dynamic unbalance with gyroscopic effect on vibrations of a laboratory centrifuge.
Design/methodology/approach. Vibrations take into account six degrees of freedom. The model of a gyroscope accepted in article is calculated on its use at the solution of a number of applied tasks.
Findings. When static and dynamic unbalance considered, the amplitudes have discontinuity when the frequency coincides with the rotation own oscillation frequency.
Originality/value. This research was important and original in field of vibrations of medical machines, which usually work with high values of frequences. It shows changes of amplitudes depending on work frequence. It can help to avoid a resonance during operation.References
