Theoretical Studies of Influence of the Configuration on the Function of Planetary Gear Inerter for Rotating Drivetrain

open access: goldInternational Journal of Automotive Engineering, 2018
In this study, authers theoretically discussed the difference in the function between two types of planetary gear inerters by comparing two fundamental functions of planetary gear inerter, one is “ideal inerter function” and another is “moment of inertia

Work of the planetary gear trains as differentials and their capabilities [PDF]

open access: yesMATEC Web of Conferences, 2019
Planetary gear trains can work differently, namely, with F=1 degree of freedom, i.e. as reducers or multipliers, and also with F=2 degrees of freedom, i.e. as differentials.

Research Progress on the Dynamic Characteristics of Planetary Gear Transmission in a Non-Inertial System

open access: yesMachines, 2023
Planetary gear systems have many advantages over other gear systems. Previous studies on its dynamic characteristics mostly used Earth as the reference system, which is inconsistent with the actual working conditions of many planetary gear systems, such ...
