本文介绍了柔性轴的非线性动态行为。轴安装在两个轴颈轴承中，轴向载荷由流体动力推力轴承支撑。特别研究了轴向推力轴承行为与轴弯曲振动之间的耦合。该轴采用典型的梁有限元进行建模。流体支撑的动态行为被认为是非线性的。使用非稳态时间积分程序来分析动态行为。本文展示了轴的轴向动态行为和弯曲振动之间的耦合。
This paper presents the nonlinear dynamic behavior of a flexible shaft. The shaft is mounted in two journal bearings and the axial load is supported by a hydrodynamic thrust bearing. The coupling between the axial thrust bearing behavior and the bending vibrations of the shaft is studied in particular. The shaft is modeled with typical beam finite elements. The dynamic behaviors of the fluid supports are considered as nonlinear. The dynamic behavior is analyzed using an unsteady time integration procedure. The paper shows the coupling between the axial dynamic behavior and the bending vibrations of the shaft.
