研究结果表明，第一级星轮及其所在轴轴承偏心误差对系统载荷不均匀系数的影响最大；
The results show that the run-out errors of the first stage planet gear and its bearing have the most significant effect on the load sharing coefficient.
随着星轮个数增加，系统载荷不均匀系数增大。
The load sharing coefficients of the two stages are increased with the number of planet gears.
将此方法应用于复合材料加筋结构的冲击载荷识别，加筋结构等效为材料性质不均匀分布的层板结构，采用假设模态法建立正向冲击响应模型。
