| Abstract: | Various typical dry friction dampers in aero-engine were summarized, and different typical dry friction models and contact kinematics models as well as their merit, demerit and range of application were introduced. Various computational methods to obtain the response of dry friction system were reviewed, and the multi-harmonic balance method combined with an alternating frequency-time domain method procedure was introduced in detail for particular interest. Furthemore, the key points of alternating frequency-time domain procedure, such as the arc-length continuation, were introduced. In the end, the difficulties and research directions in this research field were discussed. |
