液体静压多腔径向轴承动态性能参数和稳定性——北京航空学院谢沛霖、陈燕生,1989 随着液体静压轴承应用的推广和工况的复杂化,动态性能的研究日益受到重视并取得了进展。静态稳定性的某些研究表明,固定节流静压轴承是恒稳的,且动刚度总是大于静刚度。多腔径向轴承作为一种动静压混合轴承,动压作用虽然提高了承载性能但也带来了失稳的可能,其动态稳定性如何?从抑制油膜自激荡的角度来看,静压轴承的外部加压对轴颈所形成的预载作用,如同动压轴承从孔型上设法使轴颈预载一样,正是抑振的方式之一。对这种外加压预载作用,过去着重研究了它所产生的油膜刚化效果,现在则要去探讨它对油膜稳定性的作用。
Hydrostatic Multi-Cavity Radial Bearing Dynamic Performance Parameters and Stability --Beijing Aviation College Xie Peilin, Chen Yansheng, 1989 With the popularization and application of hydrostatic bearing applications, the research on dynamic performance has drawn more and more attention progress. Some studies on static stability show that fixed-throttle hydrostatic bearings are constant and their dynamic stiffness is always greater than static stiffness. Multi-cavity radial bearings as a dynamic and static pressure hybrid bearings, although the dynamic pressure to improve the bearing performance but also brought the possibility of instability, and its dynamic stability? From the inhibition of oil film self-oscillation point of view, static pressure bearings External pressure on the neck formed by the pre-load role, as dynamic pressure bearing from the hole to try to make the same journal preload, vibration suppression is one of the ways. For this external pressure preload, in the past, it focused on the effect of oil film rigidification, and now it is necessary to explore its effect on the stability of oil film.
