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

摘要

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 redistributing function.” According to the formulation of each planetary gear inerter, different characteristics were confirmed in the ideal inerter function and the moment of inertia redistributing function between two types of planetary gear inerters. Numerical simuration results demonstrated the importance of selection of the proper configuration for a planetary gear inerter in order to tune the frequency characteristics of the torsional vibration system. In addition, practical design issues of the planetary gear inerter could be successfully solved by introducing another type planetary gear inerter.
