摘要
为了消除水轮发电机组在运转中不平衡力的影响，减少机组的振动，采用３次启动法对大长径比水轮发电机进行动平衡试验，找出了失衡方位和失衡量的大小，然后加以配重，这是一种有效的消振方法。
In order to eliminate the unequilibrium forces for the hydraulic generator during operation and to mitigate vibration, the dynamic experiment was carried out with three times initiating, so that the position and quantity of unequilibrium were found. Matching the unequilibrium forces is an efficient way to mitigate vibration. It is a simple, practical, accurate method, which may be applied in large numbet of fields.
