| 摘 要： | 为了充分揭示碰摩转子系统复杂的非线性动力学行为,将多初始点分岔分析方法应用于碰摩转子—轴承系统的研究当中。通过对给定参数下转子系统响应的数值模拟,发现了比单初始点算法更加丰富的非线性现象,在一定的参数范围内该碰摩转子系统有多吸引子共存,并对解的演化过程进行了研究,结果很好地解释了碰摩转子系统中一些复杂的非线性现象。

| Abstract: | With a view to observe the complexity nonlinear phenomena of a rotor-bearing system with rub-impact,the multi-initial condition bifurcation analysis method was used in the study.And more abundant nonlinear phenomena were found than that of the single initial point integration method by the numerical simulation of the rub-impact rotor-bearing system in definite parameters.It was shown that multiple attractors coexisted in a range of parameters.Meanwhile the solution variation was also studied,which effectively explained the complex nonlinear phenomena of the rotor-bearing systems. |
