【摘要】 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。更多还原

【Abstract】 Considering the gyroscopic effect of system,a dynamic model of ball bearing supporting system including rubbing fault was established.Behaviors of bifurcation and chaos are analyzed by shooting for the systems excited different rubbing clearances.It is shown that the system experienced the process of movement which involved chaotic motions,periodic motion,quasi-periodic motion,chaotic motions,and periodic motion,with the increase of rubbing clearance.And the influence of system dynamics behavior are remarkable with rubbing clearances.更多还原
