Gear transmissions have always been a subject of study for many different reasons which
change due to the constant evolution of technology. Consequently, new topics must be …

The centrifugal effect is a natural phenomenon in rotor dynamics, significantly changing the
deformation responses in high-speed conditions. However, this phenomenon is generally …

For the simulation of the tooth contact of helical gears, a precise determination of the length
of the line of contact is required, which is variable throughout the meshing cycle. This …

The load distribution, transmission error, and time-varying meshing stiffness of spur gears
are all influenced by the teeth dimensions and profiles shape. Any modification on the teeth …

Analytical models of load distribution ratio (LDR) and meshing stiffness for orthogonal spur-
face gear drive under point contact are established to provide the parameter basis for …

The centrifugal effect is one of the most common phenomena in rotor dynamic systems,
while typically ignored in the mesh stiffness evaluation by many research papers. Focusing …

The rapid development of electric drives technology presents new challenges in the domain
of vibration and noise suppression within gear trains. Dynamics modeling serves as a …

A novel two-part gear tribodynamic model considering tooth profile modification (TPM) is
established. One part is a coupling model of gear dynamics and elastohydrodynamic …

Focusing on the accurate size, direction and position of dynamic meshing impact, an
innovative semi-finite element method (semi-FEM) forecasting model is proposed for spiral …

Backlash induces gear-teeth separation or back-side tooth mesh (BTM), resulting in gear
disengagement (GD), which heavily aggravates the dynamic performance and transmission …
