关于发电机抖动的原因分析

Analysis on The Cause of Generator Jitter

文章通过分析发电机和支架的模态频率,结果小于发动机最大转速时的点火频率,当在发电机支架上增加支撑点,系统模态频率明显改善,说明发电机抖动是系统模态频率低而产生系统共振导致。

In this paper, by analyzing the modal frequency of the generator and the bracket, the result is smaller than the ignition frequency at the maximum engine speed, when the support point is increased on the generator bracket, the modal frequency of the system is obviously improved, indicating that the generator jitter is due to the system modal frequency low and resulting in system resonance.
