转子系统振动特性演化规律研究
Study on the Evolution Law of the Dynamics Characteristics of Rotor Systems
摘要
Abstract
The dynamic model of a Jeffcott rotor system is established based on the impact theory and analyzed by the modern nonlinear dynamics and bifurcation theories. The no rub-impact, the rub-impact boundary and the stable boundary are determined. The influence of the system parameters such as damping radio and eccentricity on the evolution law of the dynamics characteristics of the rotor system is studied. Several kinds of evolution are then obtained in the parameter spaces of the damping radio and eccentricity, and the evolution law of the dynamics characteristics of the rotor system with the changing of rotational speeds is given. These results provide an opportunity for a better understanding of the relationship between the system parameters and the dynamical characteristics, such as periodtc no-rub motion, the synchronous full annular rub motion, partial rub motion, the dry whip as well as the jump phenomena.关键词
