考虑系统的陀螺效应,建立含碰摩故障的滚动轴承支撑的系统动力学模型。利用打靶法分析系统在不同碰摩间隙下的分叉和混沌行为。分析表明系统随着碰摩间隙的增大,经历了混沌运动、周期运动、拟周期运动、再到混沌运动、最后进入正常周期运动的过程,且碰摩间隙对系统的动力学行为有较大的影响。 Considering the gyroscopic effect of the system, a system dynamics model of rolling bearing support with rub-impact failure is established. Using the shooting method, the bifurcation and chaos behavior of the system under different rub-impact clearances are analyzed. The analysis shows that the system goes through chaos, periodic motion, quasi-periodic motion, and then to chaotic motion with the increase of the rubbing clearance. Finally, the system enters into the normal periodic motion, and the rubbing clearance has a great effect on the dynamic behavior of the system Impact.
