摘要: 本文通过对一个轴承组件结构在预载和非预载情况下所进行的动态试验,发现轴承组件在这两种情况下具有不同的非线性特征。文中阐述了非线性系统的双谱分析、细化双谱分析等方法,给出双谱的快速估算公式,并利用双谱和细化双谱对轴承组件的试验结果进行分析,得到一些有关轴承组件动态特笥的重要结论。

Abstract: In this paper, some dynamical tests are made for a bearing assembly in preload and non-preload and different nonlinear features of both states of the bearing assembly are detected. The analysis methods of bispectrum and zoom bispectrum are discribed. The fast estimating formulas of bispectrum are developed. The test results of the bearing assembly are analysed by means of bispectrum and zoom bispectrum methods. Finally, we obtain some important conclusions about the bearing assembly.
