Amplitude modulations in planetary gears

Wind Energy, 2012
ABSTRACTA planetary gear set introduces complicated gear vibration frequency structures, especially in sequentially phased planetary gear sets. Frequency components from a fixed sensor can be enhanced and/or canceled with different planets and ring gear configurations.

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes

Chemie Ingenieur Technik, EarlyView.
A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,

Modeling, Testing, and Characteristic Analysis of a Planetary Flywheel Inerter

Shock and Vibration, 2018
We propose the planetary flywheel inerter, which is a new type of ball screw inerter. A planetary flywheel consists of several planetary gears mounted on a flywheel bracket. When the flywheel bracket is driven by a screw and rotating, each planetary gear
