作者： 孙政策 徐健学 周桐 谭宁 State Key Laboratory of Mechanical Structural Strength and Vibration Xi' an Jiaotong University Xi' an 710049 P. R. China Department of Mechanics Fudan University Shanghai 200433 P.R.China State Key Laboratory of Mechanical Structural Strength and Vibration Xi' an Jiaotong University Xi' an 710049 P. R. China State Key Laboratory of Mechanical Structural Strength and Vibration Xi' an Jiaotong University Xi' an 710049 P. R. China mathematical model of an impacting-rub rotor system with bending-torsion coupling was established. It was compared with the model without bending-torsion coupling through the modem nonlinear dynamic theory . It is observed that periodical chaotic period adding phenomena in them and the two models have a similar bifurcation process in their bifurcation figures . But the influence of bending-torsion on the dynmaic characteristics of the system is not neglected. The results have considerable meanings to analyze and improve the characteristics of an impacting- rub rotor system .
