Research on vibration problem of integral mistuned bladed disk assemblies at home and abroad

Mistuned integral bladed disk assemblies, including the mode, the vibration transmission localization and the localization factors, were elaborated. Besides, the modeling and solving methods of mistuned bladed disk assemblies were discussed. The mainly related hot topics, the latest research methods and their achievements in recent 10years, were reviewed and investigated in detail, including: nonlinearity, flutter, sensitivity, pneumatic and structure coupling, mistuning identification and prediction, mistuning optimization, intentionally mistuning, multi-stage and multi-component disks coupling, Coriolis forces, reliability and robustness etc. Finally, potential topics for future research work were proposed, for instance, building a more effective and applicative model with higher precision, verifying theoretical simulation with the test method, impact on multi-stage and multi-component integral bladed disk assemblies of pneumatic and structure coupling as well as the shroud tip and friction coupling, the principle of Coriolis forces, insensitivity and robustness to the mistuning of bladed disk assemblies and so on.
