Chaotic vibrations in gear mesh systems

Jan Łuczko
The paper is concerned with qualitative analysis of a non-linear model describing vibrations of a gear mesh system. The influence of selected parameters on the character and level of vibrations is studied. The possibility of excitation of quasi-periodic or chaotic oscillations for some regions of the parameters has been shown. Different types of vibration are illustrated by plots of time histories, phase portraits, stroboscopic portraits and bifurcation diagrams.
Keywords: non-linear vibration; chaos; gear
