摘　　要：比较了汽轮机阻尼结构整圈连接叶片与其它结构叶片从振动概念、特点、共振危险性的区别等方面的异同点,提出了汽轮机阻尼结构整圈连接叶片带节径振动比较合适的称谓,并介绍了相关汽轮机阻尼结构整圈连接叶片失效事故,提出了评价汽轮机阻尼整圈结构连接叶片安全性的一阶带节径系统振动静频合格范围等。Comparing on the vibration concept, characteristic, and resonance risk between damped structure round linking blades and other structure blades, this article puts forward a more appropriate appellation of one diameter mode vibration of damped structure round linking blades. It also introduces the damped structure round blades connection failure, and normal range of the first-order Wbration frequency to evaluate the safety of damped structure linking blades.
