摘要
本文讨论了在不施加人工激振的前提下,处于工作状态的转子系统流体动压滑动轴承油膜刚度及阻尼参数的现场识别方法.由于是在油膜的正常工作状态下识别其参数,所得结果更加接近于真实情况.此外,该方法还可以作为一种现场动平衡方法.
Presupposing that the manual excitation is not applied, a method for identifing dynamic coefficients of hydrodynamic lubricating journal bearings which support a rotor in running-state in the on-site condition is investigated in the paper. Because the identification procedure is carried out in the natural state of oil films,the results obtained are close to the true values. Moreover,the method can also be taken as an field balancing method.
