摘　　要：通过对人字齿行星齿轮传动系统多重啮合间相位关系的分析,给出了考虑啮合相位的时变啮合刚度计算公式。考虑误差激励和时变啮合刚度激励,在行星架随动坐标系中建立了人字齿行星齿轮传动系统的平移-扭转耦合动力学模型。针对两组不同啮合相位的行星齿轮传动系统,采用傅里叶级数法求解其动力学模型,得到频域解和时域解,且分析啮合相位对人字齿行星齿轮系统振动特性的影响。PGT,The formula for the time-varying meshing stiffness is deduced from the analysis of the mesh phasing relation ships in the herringbone planetary gear train（PGT） .The transverse-torsional modal of herringbone PGT is established in the rotating coor- dinate system, in consideration of the error and meshing stiffness excitation. By solving the modals of PGT systems with different meshing phasing relationships, time and frequency domain solution can be obtained;moreover, the effect of the mesh phasing rela- tionships on the vibration characteristics of the herringbone PGT is analyzed.
