| Abstract: | Based on various difficulties in study on vibration localization mechanism of bladed disks with mistuned non-linear friction damping,especially the problems like establishment and solution of non-linear mechanical model,the mechanical model of bladed disks with random mistuning of hysteretic dry friction damping was established in this thesis,and an incremental harmonic balance method was used to analyze the effects of parameters of bladed disks like degree of mistuning of dry friction force,coupled stiffne... |
