Matlab Higher-Order Spectral Analysis on Bearing Data |
| |
| Abstract: | In this paper, we make an analysis of the bearings vibrating data by using matlab Higher-Order Spectral Analysis(HOSA) method, and introduce the mathematical basis of HOSA and its functions. Because of the non-Gaussian and non-Linear properties of bearing data, low-order statstics can not be used to analyze the vibrating features, while higher-order spectrum and HOSA can, which is demonstrated in this paper. |
