径向固定瓦滑动轴承动特性计算及分析

Calculation and Analysis of Dynamic Characteristics of Radial Fixed Bearing

以径向固定瓦滑动轴承为研究对象,研究载荷和转速对轴承动特性的影响。针对上述目的建立径向固定瓦滑动轴承的数学模型,并基于有限元法对相关方程进行数值求解。通过该方法获得了载荷和转速对径向固定瓦滑动轴承动特性影响的相关规律:动特性系数基本上随转速增加而有所减小,随比压增加而增加,但也因方向的不同导致其变化的幅值出现较大差异。

In this paper, the influence of load and speed on the dynamic characteristics of the radial fixed bearing is studied. The mathematical model of the radial fixed bearing is established. Based on the finite element method, the relevant equations of the mathematical model are solved by numerical method. Thus we obtain the relevant rules of dynamic characteristics： dynamic coefficient basically decreases with speed increasing, increases with load increasing. However amplitude of the change is also a large difference because of the different direction.
