动压滑动轴承油膜动特性研究是转子动力学中的重要课题,经过近20年来的研究,建立了一套理论及相应的计算和实验方法,取得了许多进展,但也还存在一些问题,本文想做一概略性评述,谈一点不成熟的看法。 1.回顾 动压滑动轴承支承的高速回转机械转子振动是设计和生产中的关键问题,人们希望能够预测或判断转子的稳定性,可用力学分析方法把转子-轴承系统简化成一定的力学模型,列 Dynamic pressure sliding bearing oil film dynamic characteristics of the rotor dynamics is an important issue, after nearly 20 years of research, established a set of theory and the corresponding calculation and experimental methods, made a lot of progress, but there are still some problems, this article Want to make a rough comment, to talk a little immature opinion. 1. Reviewing the rotor vibration of high speed rotating machinery supported by dynamic pressure sliding bearings is a key issue in design and production. People hope to predict or judge the stability of the rotor. The mechanical analysis method can be used to simplify the rotor-bearing system into a certain mechanical model, Column
