The Effect of Group Number and Group Coupling Stiffness on Vibration Response Localization in Tuned Grouped Blade-disk

摘要：

　　The group number and group coupling stiffness are important structural parameters of the grouped blade-disk.This work examines how the group number and group coupling stiffness affect the vibration response localization of tuned grouped blade-disk.The lumped parameter model of the grouped blade-disk was established, and the vibration equation was derived.The vibration response localization factors of tuned grouped blade-disks were obtained at the different group number and group coupling stiffness, and the effects of group number and group coupling stiffness on vibration response localization was analyzed.The results show that the vibration localization appears in the tuned grouped blade-disk and the degree of vibration response localization reduces with the increasing of group number and group coupling stiffness.The results can help to completely reveal the localization mechanism of the grouped blade-disk.
