圆柱轴承8个动力特性参数(刚度和阻尼)的计算
已知普通圆柱轴承直径D=0.1016m,径向间隙c=5.08*10^(-5)m,长度L=0.0254m,油膜黏度u=6.9*10^(-3)Ns/m^2,静载荷F=395.45N. 请教大神们,如何根据这些参数计算轴承的4个刚度系数和4个阻尼系数,小弟不胜感激! 返回小木虫查看更多

亲,你现在解决了吗
还没有呢!大神求赐教
原文:‘The journal diameter is 4 in., the radial clearance is 0.002 in., the bearing length is 1 in., the oil viscosity is 6.9 centipoise, and the bearing load, equal to half the shaft weight, is 88.9 lb. For this type of bearing there are four stiffness coefficients and four damping coefficients which are functions of the bearing Sommerfeld number and, therefore, depend on the rotor speed‘。说四个刚度系数和四个阻尼系数是Sommerfeld number的函数,我查了半个月的文献,也没有找到相关的公式

给你一本参考书,小木虫也有下载:滚动轴承分析
谢谢,不过这是普通圆柱滑动轴承的支承特性计算
看书学习啊
