An approach to analyze the effects of different factors on gear dynamic behavior is presented by means of vibration influence chart. Considering the high contact ratio and heavy load characteristics of herringbone planetary gear train, a translational-rotational coupled dynamic model for an encased differential herringbone planetary gear train is developed using lumped mass method. The principles and methods to draw the influence chart are given and the specific steps for HPGT are discussed in detail. The optimal matches between the mean value and fluctuation of mesh stiffness, rotating speed are obtained using the vibration influence charts. The good design regions for vibration are evidently presented in figures, which is significant to parameters design of herringbone planetary gear systems.
