This article summarizes published journal articles on planetary and epicyclic gear dynamics
and vibration. Research in this field has increased dramatically over the past two decades …

This paper provides a tutorial and summary of the theory of circulant matrices and their
application to the modeling and analysis of the free and forced vibration of mechanical …

行星齿轮箱广泛用于风力发电, 直升机, 工程机械等大型复杂机械装备中, 低速重载的恶劣工作
环境经常导致其太阳轮, 行星轮, 行星架等关键部件出现严重磨损或疲劳裂纹等故障. 然而 …

Vibration has been and still is a persistent problem to negate the transmission accuracy and
service life of rotate vector (RV) reducer, and vibration analysis remains a challenge in …

In the currently booming market of wind turbines, a clear focus is put on the design of
reliable and cost-effective subsystems, such as the gearbox. A requirement for reliable …

In this study, the dynamic responses of a planetary gear are analyzed when component
gears have time-varying pressure angles and contact ratios caused by bearing …

Experimental modal analysis techniques are applied to characterize the planar dynamic
behavior of two spur planetary gears. Rotational and translational vibrations of the sun gear …

Planetary gears are parametrically excited by the time-varying mesh stiffness that fluctuates
as the number of gear tooth pairs in contact changes during gear rotation. At resonance, the …

The highly structured modal properties of planetary gears having diametrically opposed
planets and an elastic ring gear are illustrated and mathematically proved in this work. Two …

An original lumped parameter model of planetary gears is presented which accounts for
planet position errors and simulates their contribution to the quasi-static and dynamic load …
