The rotational periodicity of bladed disk assemblies can be destroyed by manufacturing process, material, a consequence of in service wear and other reasons, so it will lead to mistuning or disorder called by literature. It is found that, unlike the tuned system having a particular number of several nodal diameters, the mistuned bladed disk system has modes, which are always complex in shape.

The rotational periodicity of bladed disk assemblies can be destroyed by manufacturing process, material, a consequence of in service wear and other reasons, so it will lead to mistuning or disorder called by literature. It is found that, unlike the tuned system having a particular number of several nodal diameters, the mistuned bladed disk system has modes, which are always complex in shape. Slight variations in the geometry and material properties of the system can cause large changes in its mode, and, consequently, its dynamic response. In this paper, based on the modal synthesis technique and general finite element program, a 3D FE model of a mistuned bladed disk system with 16 blades has been set up for the determination of the free vibration characteristics. The effects of frequency standard deviation and coupling strength on vibration are also given.

Cyclic symmetry in bladed disc is often destroyed by difference in blade structural properties and this results in mistuning.The effect of centrifugal force on the mistuning of bladed disc was investigated by three dimensional finite element analyses.Vibration characteristics of mistuned bladed disc caused by random Young's moduli in all blades were also investigated by probability method.The results indicate that the cen- trifugal force reduces the localization.As Young's moduli of blades are in the tolerance...

Cyclic symmetry in bladed disc is often destroyed by difference in blade structural properties and this results in mistuning.The effect of centrifugal force on the mistuning of bladed disc was investigated by three dimensional finite element analyses.Vibration characteristics of mistuned bladed disc caused by random Young's moduli in all blades were also investigated by probability method.The results indicate that the cen- trifugal force reduces the localization.As Young's moduli of blades are in the tolerance of 5%,the bladed disc can be treated as a cyclic symmetry structure.

为了研究失调叶片——轮盘系统振动特性,建立了某汽轮机失调叶片——轮盘的三维实体有限元模型,研究了离心力对失调叶片——轮盘系统振动的影响;利用概率分析方法,研究了所有叶片弹性模量在5%误差范围内随机失调叶片——轮盘振动情况.结果表明,离心力对失调叶片——轮盘系统局部化振动有减弱作用;所有叶片弹性模量在5%误差范围的随机失调系统,其固有频率与非失调相差很小,即失调叶盘系统可以按照循环对称结构进行模态分析.
