Rotational Driving Response Simulation of Planetary Gear Mechanism for Differential Meshing Conditions

Abstract

Although planetary gear mechanisms are used in many machines, their dynamic characteristics have not been fully elucidated because they have multiple input-output relationships and planetary motions with different meshing states. Therefore, we attempted to model the planetary gear mechanism to clarify the influence of internal phenomena on external phenomena. In this study, to dynamically model the planetary gear mechanism, we proposed a method to draw a block diagram from the equations of motion of each element and simulate the response characteristics of the planetary gear mechanism. The validity of the simulation method was compared with that of the resonance frequency.
