Abstract

Difficulties in obtaining ? by means of known methods - the proper estimation of maximum amplitudes in the transient resonance of technical systems, were indicated in the paper. It was proved that models of 1 degree of freedom cannot be used for such systems. The energy method of estimating maximum amplitudes in the transient resonance - useful also for systems of several degrees of freedom and multiple drives - was proposed. Taking into account interactions between the rotor and body motion of vibratory machines case the nomogram method for investigating resonance amplitude for coast-down phase was also presented.
