摘要：
A transient dynamic finite element model of disc-pin system was established with finite element analysis(FEA) software ABAQUS. The transient dynamics FEA model successfully predicted the disc and pin motion state, the frictional contact state and feed in energy of the system as well as nonlinear frequency coupling phenomenon of the disc-pin frictional self-excited vibration system. Results showed that, there existed simultaneously warp caused by mechanical action and high frequency normal vibration on disc. Vibration mode of the pin rod was bent-based, supplemented by torsional vibration, and had pure sliding limit cycle. The contact pressure distribution had periodic variation characteristic, and the normal and friction force influenced the frequency. There existed simultaneously feed-in and feed-out energy in the system, and the feed-in energy which was dominant in the system caused friction squeal.
