Abstract: | This paper propose to collect surface displacement signals of bearing by high-precision eddy current sensor and use approximate entropy index for signal analysis , and ultimately assess the rolling bearing dynamic quality .Experimental results show that the proposed method can clearly identify the location and types of bearing defects , it could provide a reference to the actual production . |

Keywords: | rolling bearing dynamic detection approximate entropy displacement signal |
