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.
