汽轮发电机组安装与轴系振动的关系探讨

从机械性的干扰力,电磁干扰力,系统的刚性不足,由蒸汽力引起的间隙自激低频振动,动静部分磨擦等五个方面来探讨汽轮发电机组轴系振动与安装的因果关系,重点从安装角度就如何防止机组轴系振动过大提出了见解。

Analysis the relationship between the vibration and installation of turbo-generator bearing from five aspects. These aspects are the perturbation of mechanical,the elcetromagnetic interference,the shortage of stiffness of the system.the interstitial auto-exciting low frequency vibration caused by steam power and the rubbing the sound of part. Some opinion on how to prevent generator shaft vibration strength especially from the way of installation are raised.
