INTERACTION OF VIBRATING SYSTEM AND ENERGY SOURCE

Abstract eng:
Majority of publications on mechanical vibrations are based on the assumption that the external excitations is produced by an ideal source of power with prescribed frequency. But in reality, the excitation sources are non-ideal with limited power, limited inertia and their frequency fluctuates according the instantaneous state of oscillating system. The paper presents on overview of systems and results gained during the several dozens of years on this interaction problem. The most characteristic properties of systems excited by source of limited power and limited inertia are variation of revolution, distortion of harmonic motion, instability and non-uniform passage through resonance zone.
