摘　　要：本文考虑了两自由度的非线性局部碰磨转子系统,在原系统的无量纲模型的基础上,用Lyapunov-Flo-quet变换这一解析方法得到便于研究其分岔行为的形式,并用高维分岔理论研究系统的局部分岔行为。Two-degree of freedom nonlinear local rubbing rotor system is investigated in this paper. Based on the non-dimensional form of the system, we apply Lyapunov-Floquet transformation which is an analytic method to get the form, which makes bifurcation analysis easy. And we use high-dimensional bifurcation theory to analyze in details the local bifurcation behavior.

关 键 词：局部碰磨转子 Lyapunov—Floquet变换 分岔
