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，即失调叶片—轮盘系统可以按照循环对称结构进行模态分析。

By use of the Benfield-Hurda modal synthesis method, the structural model of mistuning blade-disk assemblies is established.

用Benfield—Hurda的混合型模态综合法，给出了非谐调叶盘的特征解方程。

The coupling effect of both mistuning by non-linear dry friction scatter and by blade stiffness on system response was also studied.

同时对叶片的非线性干摩擦阻尼的散乱失谐和刚度失谐的耦合影响进行研究，总结含有非线性干摩擦阻尼的失谐叶盘系统的受迫响应规律。

These variations, which arereferred to mistuning, mainly come from the blade procession, wear in service, etc.

失谐主要来自于叶片的加工误差、运行磨损等。
