【Abstract】 This paper presents a method for formulating dynamic lubrication schemes based on grey relational degree. Based on the wind speed prediction data,the basic bearing lubrication scheme is formulated with the rotational speed as the main operating parameters. Then the lubrication scheme is dynamically adjusted according to the comparison of actual wind power and predicted data. Firstly,the wind speed is analyzed based on the time series,and the typical components are selected as the reference sequence. Then the wind speed component is determined by the grey relativity calculation method. The bearing condition is determined according to the relationship between the wind speed and the speed,and the corresponding lubrication scheme is formulated. Finally,the corresponding physical experiments are done according to the data analyzed,and the results of physical verification preliminarily show the effectiveness and practicability of the dynamic lubrication scheme.更多还原
