Gearbox is widely used in industrial and military applications. Due to high service load,
harsh operating conditions or inevitable fatigue, faults may develop in gears. If the gear …

In this paper, the progress in nonlinear dynamics of gear driven systems in the past twenty
years is reviewed, especially the gear dynamic behavior, by considering the backlash and …

The occurrence of a crack could change the gear mesh stiffness and consequently influence
gear vibration properties. Cracks may occur on the tooth root and tooth surface, but the …

The present work investigates dynamics of a gear-pair system involving backlash and time-
dependent mesh stiffness. In addition, the system is under the action of external excitation …

A number of experiments on a physical system with clearance having combined parametric
and external forcing excitation are presented. The data demonstrate several nonlinear …

In the previous nonlinear dynamic models of spur gear system, when considering bearing
deformation, the pressure angle and gear backlash are usually considered as constants to …

A mechanical system exhibiting combined parametric excitation and clearance type non-
linearity is examined analytically and experimentally in an effort to explain complex behavior …

This paper concentrates on the gear tooth crack detection by investigating the effects of tooth
crack on the vibration behaviors of a nonlinear spur gear system. Firstly, an analytical tooth …

Time-varying mesh stiffness is one of the main excitation sources of a gear system, and it is
also considered as an important factor for the vibration and noise of gears. Thus, this …
