失谐叶片-轮盘结构系统振动局部化问题的研究进展

对近２０年来国内外关于失谐叶片－轮盘结构系统振动局部化问题研究的进展进行了较为详细的评述和讨论，文中首先说明了振动局部化问题的基本概念，然后对失谐叶片－轮盘结构系统模态局部化和动态响应局部化在分析模型、求解方法及其基本性质和规律等方面的研究进展进行了较为全面的评述，最后提出了今后应深入研究的问题．

VIBRATORY LOCALIZATION OF MISTUNED BLADED DISK ASSEMBLIES------A REVIEW

This paper reviews the state of the art in the vibratory localization of mistuned bladed disks in the past three decades with regard to modal localization and response localization. Blade-to-blade variations (called as mistunings) in their geometry and structural properties occur during the manufacturing process and/or as a consequence of in-service wear. Although small under certain conditions they may localize the vibratory mode and confine the response to a region near the source. Since mistunings can re...
