摘要
从一个由三个函数确定的非稳态油膜力的非线性模型出发 ,以短轴承支撑的弹性转子系统作为研究对象 ,采用短轴承油膜力的解析表达式和数值模拟的方法研究了系统的分岔和混沌特性。
The stability of an elastic rotor supported by short journal bearings is discussed, focusing particularly on its nonlinear aspects. A more reasonable nonlinear unsteady oil film force model, which is determined only by three functions, is adopted and the explicit analytical formula of oil film force for short journal bearing is used for bifurcation and chaos study.
