The main purpose of condition monitoring in gear systems is to facilitate condition-based
maintenance (CBM) by detecting the degradation of components, eg gear teeth, before the …

The existing lumped parameter model was commonly used to analyze the non-linear
dynamics of gear systems, in which stiffness excitation and error excitation due to …

This work describes an advanced model for the analysis of contact forces and deformations
in spur gear transmissions. The deformation at each gear contact point is formulated as a …

Gearbox is required to serve for≥ 30 min in helicopter design to improve survivability, when
the gear drive loses lubrication due to battle damage. Under such loss-of-lubrication …

The uncertain variables of the link dimensions and joint clearances, whose deviation is
caused by manufacturing and assembling errors, have a considerable influence on the …

The gear foundation is commonly assumed to be a rigid body in analyzing the dynamic
characteristics of the gear system. This modeling approach may not be appropriate for …

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 …

The meshing surfaces of a gear pair are rough from a microscopic perspective and the
surface topography will affect the dynamic response. To study the influence of real surface …

For the purpose of simulation and vibration-based condition monitoring of a geared system,
it is important to model the system with an appropriate number of degrees of freedom (DOF) …

In the traditional gear dynamic model, the mesh stiffness is obtained under static load. When
the mesh stiffness changes greatly with the change of load, the traditional dynamic model is …
