For vibration analysis of aeroengine blisk structure, a prestressed component modal synthesis (CMS) super-element method is put forward with the fixed interface prestressing and free interface super-element approach.
Based on this method, natural vibration characteristics of blisk structure are calculated at different modal truncation numbers.
Comparing with the accurate result of global method, the selection principle of modal truncation number is obtained which affects the accuracy of prestressed CMS super-element method.
Vibration response of two-stage blisk structure is calculated by this method, and the effects of different blade aspect ratios have been discussed on vibration characteristics.
The results show that prestressed CMS super-element method is in the high accuracy and efficiency on blisk vibration analysis.
Resonant frequencies in vibration response are nearly the same between the first-stage blisk and the second-stage blisk, and they are both approximately located in the range 588 Hz–599 Hz.
The maximum displacement and dynamic stress are at blade tip and root of the first-stage blisk, respectively.
Blade aspect ratio is a key factor of blisk vibration; the effects of blade aspect ratio on natural frequencies are different in the conditions of fixed width and fixed length.
This research provides the theoretical basis for dynamic design of aeroengine compressor rotor system.
