Comparative Study of Perturbation Methods for the Forced Vibration of Mistuned Bladed Disks
【摘要】 基于质量-弹簧模型,研究了在不同系统参数下,经典摄动法、修正摄动法和自适应摄动法求解失谐叶盘系统受迫响应的应用特点。通过对3种摄动法计算结果的比较分析,确定了3种摄动法对不同失谐强度、耦合强度、粘性阻尼比等参数的适用条件和应用特点。因此,本文的结论对于应用不同摄动法在求解失谐叶盘系统受迫响应问题时具有指导意义。
【Abstract】 The application of classical perturbation,modified perturbation and adaptive perturbation methods are investigated on the basis of a mass-spring model to obtain the forced response of a mistuned bladed disk under different system parameters.The proper application conditions of different mistuning degree,coupling degree and damping ratio are determined by comparing and analyzing the results obtained from the three perturbation methods.Therefore,the conclusions of this paper have important significance for the application of these three methods to investigate the forced response of mistuned bladed disks.
