| 摘 要： | 用近代非线性动力学理论分析了支承有间隙的调整对对称刚性复合转子系统的复杂运动，用数值方法得到系统在某些参数区域内的轴心轨迹图、Poincare映射图和分岔图，讨论了转速变化时出现的周期、倍周期、拟周期和混沌运动，分析结果为定性地改善转子系统的稳定运动状态提供了理论依据。

| Abstract: | Modern nonlinear dynamical system theory is used to analyze the complicated motion of a nonsymmetrical rigid complex rotor system with pedestal looseness. In some typical parameter regions the orbit diagrams of axle center, the Poincare maps and the bifurcation diagrams of the system are acquired with a numerical integral method. Various forms of double-periodic, quasi-periodic and chaotic motion are discussed by using the rotation speed as the control parameter. The analysis result of this paper provides theoretical bases for qualitatively controlling the stable operating state of rotors. |
