Dynamic load distribution of planetary gear sets subject to both internal and external excitations

Planetary gearsets are widely used in several mechanical systems and have numerous advantages over counter-shaft gears. Despite this, the complex arrangement of components a planetary gear system makes them susceptible to noise vibration issues. An exhaustive rich literature is available on topic dynamics, but most these studies consider only parametric excitation mesh contacts while assuming an ideal power source. But contrary this popular assumption, realistic sources (IC Engine, electric motor, wind turbine, etc.) could be subjected torque fluctuations based operating conditions. The current study presents theoretical investigation load distribution dynamic behavior sets both internal external excitations. A three-dimensional model that inherently captures due elastic employed study. influence conditions system-level response local contact stress explored. Discussed results not illustrate potential also reinforce need for such computationally efficient models design analysis purposes.
