Automatic configuration analysis method of planetary gear automatic transmission
Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2023Planetary gear trains (PGT) with the aim of achieving multiple speed ratios are widely used in automatic transmission (AT). A fast configuration analysis method is of significance for improving the efficiency of AT design, and it is essential to study the automatic configuration analysis method for AT.

New Modeling of Planetary Gear Transmission
2017In a planetary gearbox, there are multiple sources of vibrations due to the complexity of the gearbox since the latter contains multiple components (Sun, Carrier, Planets, and Ring) witch all of them are in mesh. In addition, the complexity of the planets motion (two rotational motions) affects the vibration collected in experiments, because the ...

Proceedings of the Institution of mechanical engineers. Part D, journal of automobile engineering, 2023
To reveal the influence of cracks on the dynamic characteristics of a two-stage planetary gear transmission system (TSPGTS), a nonlinear dynamic model with 30-DOF in bending and torsion was constructed, taking into account parameters of different crack ...

Reliability modeling for planetary gear transmission system considering dependent failure processes
Quality and Reliability Engineering International, 2021Many mechanical systems are subject to degradation and random shock processes, which are dependent and competing. The two processes are soft failure process and hard failure process, either of which occurs will cause the system to fail.

Elastohydrodynamic Lubrication Design of Planetary Gear Transmission
Advanced Materials Research, 2011Based on elastic hydrodynamic lubrication (EHL) theory, an EHL model of the meshing between the sun gear and planet gear in planetary gear transmission was established. The EHL oil film thicknesses at meshing areas and those distributions for two operation cases were calculated: one case with the sun gear as the driving gear and another case with the ...
