Abstract: Integrally bladed disks are the key components of new-generation high-performance aero-engines and have the advantages of compactness, light weight and high thrust-to-weight ratio. Nevertheless, integrally bladed disks also possess the characteristics of low structural damping, high modal density and random mistuning issues, which lead to large vibration amplitudes during passing through the resonant regions. These issues have significantly affected the reliability and fatigue life of integrally bladed disks. In order to effectively mitigate the large vibration amplitudes of mistuned integral blisk, a dynamic vibration absorber array method is developed. The dynamic vibration absorber array consists of a series of vibration absorbers, which are then divided into several series to target multiple different modes and reduce the resonant peaks. In order to reveal the multi-mode vibration mitigation mechanism of the dynamic vibration absorber array approach, a classical lumped parameter model with 3 degrees of freedom per sector is employed for the dynamic modeling of the integral blisk-dynamic vibration absorber array system. The analytic power flow approach is also adopted for quantifying the dissipation and transition of energy between different components and adjacent sectors. On this basis, the influences of the mass, frequency tuning accuracy and damping level of the vibration absorbers, as well as the number of absorbers, on the device’s vibration attenuation performance are comprehensively investigated. A test bench of integral blisk with 12 sectors is set up, and several dynamic vibration absorbers have been designed and manufactured. Experiment has been conducted to validate the effectiveness of the dynamic vibration absorber array approach. The results show that the dynamic vibration absorber array can effectively control the blade-dominant and blade-disk coupling modes. A device with very small mass can usually acquire satisfactory multi-mode vibration attenuation performance for tuned and mistuned integral blisk, and the robustness of performance is also very good.
