摘要：

A study is made to establish the basic vibration characteristics of bladed disk assemblies. An analysis is presented and used to predict the natural frequencies and mode shapes of uniform bladed disks. It is ffound that there are many more natural frequencies than those indicated by a study of the blade cantilever modes. The effects of blade detuning are studied and found to give rise to irregular and complex modes of vibration. Consideration of the vibration characteristics under typical operating excitation conditions shows that a detuned system is susceptible to many more resonances than is an equivalent tuned system.
