对磨床主轴用高速角接触球轴承的刚度和阻尼特性进行了理论研究。同时考虑了油膜挤压效应和赫兹接触的弹性变形，提出了一个合适的动力学模型。为了验证所得到的结果，一个程序研究的动态试验磨床主轴，在受控的操作条件下，实现。理论计算结果与实验结果有较好的相关性。
A theoretical research was developed concerning the rigidity and damping characteristics of high speed angular contact ball bearings mounted on grinding machine main spindles. Both film squeeze effects and elastic deformation of the Hertzian contact were considered and an adequate dynamic model is suggested. To validate the results obtained, a program studying the dynamic state of a test grinding machine main spindle, in controlled operating conditions, was achieved. A good correlatio between theoretical and experimental results was obtained.
