两级定轴齿轮分岔与混沌特性研究
Bifurcation and Chaos Characteristics of Two-stage Gear Train Sets
摘要
Abstract
In order to investigate the chaos vibration control of a two-stage gear train,a nonlinear dynamics dimensionless equation of a two-stage gear train with time varying meshing stiffness,errors of transmission and backlashes was established and solved with the numerical method.The influences of excitation frequency and damping coefficient on the bifurcation and chaos properties of the system were analyzed with bifurcation diagram and Poincáre section.The study result shows that the system's motion state would change into chaos in the way of crisis or intermittency,the damping coefficient would influence the region of bifurcation;the two-stage gears would germinate crisis in the process of movement at the same time,while the second gear remained relatively stable at the bifurcation point.关键词
