由于装配误差的存在，行星齿轮系统的动态特性可能会与原来的理想设计相比发生变化。考虑零件的装配误差，采用集中参数法建立了风力机变速箱第一斜齿轮系统的弯扭摆耦合振动模型。然后采用变步长龙格-库塔算法对斜齿轮系统的动力学模型进行求解。研究了载体水平装配误差、载体轴向装配误差和载体空间装配误差对系统动态特性的影响。结果表明，Z轴方向的载体装配误差对系统DTE响应变化的影响比其他轴向误差的影响更大。不同方向上的载体装配误差往往会使动态网格力的动态响应变大。不同方向的托架装配误差对斜齿行星齿轮系统的频率响应有较大的影响。在载波空间装配误差(<；~2000 GHz)下，DMF的频率位置被减小。
Due to the existence of assembly errors, the dynamic characteristics of planetary gear system could be changed compared with the original ideal design. Considering the assembly errors of component, a bending-torsional-pendular coupled vibration model of the 1st helical planetary gear system in wind turbine gearbox was built using lumped parameter method. Then the variable step Runge–Kutta algorithm was applied to solve the dynamic model of helical planetary gear system. The effects of carrier horizontal assembly error, carrier axis assembly error and carrier spatial assembly error on the dynamic characteristics were investigated. Results show that the influence of carrier assembly error along thez-axis on the variations for DTE response of the system is worse than other axis error cases. The carrier assembly errors along the different directions tend to make the dynamic responses for dynamic mesh forces (DMFs) larger. The frequency responses for DMFs of helical planetary gear system are influenced comprehensively by carrier assembly errors along the different directions. The frequency positions of DMFs are reduced under carrier spatial assembly errors (< 2000 Hz).
