摘要： 为改善传统动压挤压油膜阻尼器油膜力高度非线性的不足，提出了一种新型的动静压挤压油膜阻尼器结构。在推导出新型动静压挤压油膜阻尼器油膜力近似解的基础上，从理论及试验上研究了新型动静压挤压油膜阻尼器对柔性转子系统振动的控制能力。

Abstract: An advanced hybrid (combination of hydrostatic and hydrodynamic) squeeze film damper (HSFD) concept is described to improve high nonlinearity of conventional hydrodynamic squeeze film damper (SFD). An approximation solution of fluid film-force of the deep recessed HSFD without axial slots which can suitably be used to larger journal eccentricity ratio is presented. The control ability of the HSFD to reduce rotor vibration is investigated both theoretically and experimentally with a modified Jeffcott rotor supported on the HSFD, and compared with the system supported on the SFD.

Key words: Damper, Dynamics, Rotor, Vibration control
