摘要
针对滚动轴承非线性恢复力进行分析,以某细长轴试验平台为研究对象,建立了滚动轴承-转子-基座系统模型,研究了转子系统在不同转速时的分叉特点和混沌行为,分析系统在不同状态下的信号特点,并与试验台测量结果进行了对比。
The nonliner resilience of rolling bearing - rotor is mostly considered. Taking the slight are experiment flat roof as object, a model is established for a rolling bearing - rotor - pedestal. The bifurcation characteristic and chaos behavior of the rotor system at the situation of different rotating speed of bearings are studied. At the same time ,the feature of the vibration signals in different status is analysised, and the results are compared with experiment result.
