Abstract
Disclosed is a double-layer oil film lubrication analysis method and system based on a floating bushing. The method includes: determining a roller motion track and a floating bushing motion track according to a roller displacement and a floating bushing displacement; determining, when the motion tracks are closed end to end, minimum values of inner-layer and outer-layer oil film thickness of the floating bushing according to an oil film thickness at each moment; and determining that an abnormality exists in double-layer oil film lubrication when either of the minimum values of the inner-layer and outer-layer oil film thickness of the floating bushing is less than a preset oil film thickness threshold value. According to the present disclosure, more accurate abnormality analysis of double-layer oil film lubrication can be realized.
