摘要
基本失谐模型FMM(Fundamental Mistuning Model)是以一种基于失谐叶盘结构的单模态族子集为模态变换阵的减缩方法,采用该方法建立分析模型,可以容易识别出控制失谐响应的基本参数,基于该理论在不同描述框架和假设前提的若干典型简化形式,给出了若干分析应用实例,以及这些方法的瞬态响应分析。
FMM（Fundamental Mistuning Model）is a reduced order modeling method for mistuned bladed disk structures vibration based on sigle model race.It would be simple to distinguish the basic response of mistuned parameters.Several applied simples and the transient response analysis were given in this thesis based on different describe frames and some types of simplification in using this theory.
