The invention provides a water lubrication bearing interface lubrication performance analysis method and a storage medium, and the analysis method comprises a mode determination step; a mode judgment step: initializing, estimating according to a set method to obtain a film thickness ratio parameter, judging the estimated film thickness ratio parameter, judging to be a first mode if the film thickness ratio parameter is 0 (Lambda,(A, judging to be a second mode if A is less than or equal to B, and judging to be a third mode if B is less than or equal to B; wherein A is a first set threshold value, and B is a second set threshold value; wherein the first mode is a boundary lubrication state mode; wherein the second mode is a mixed lubrication state mode; and the third mode is a fluid dynamic pressure lubrication state. The invention has the advantages of simple and clear steps and high calculation efficiency.
Description
Technical field [0001] The invention relates to the technical field of bearing interface lubrication, in particular to a water-lubricated bearing interface lubrication performance analysis method and storage medium, and more particularly to a water-lubricated bearing interface lubrication performance analysis method considering the transition of lubrication status. Background technique [0002] Scholars at home and abroad have done a lot of work on bearing lubrication performance and tribological characteristics. For example, a bearing assembly disclosed in patent document CN104235186B has a wear-resistant surface formed by an alloy including tin; it is configured to be resistant during use. The abrasive material contacted by the abrasive material, the abrasive material has a smooth surface; and a lubricant composition including one or more additives having an affinity for tin. It also provides a method of giving super lubricating properties to bearing components. [0003] However...
