Dynamic load bearing mixed viscoelastic flow lubrication performance calculation method under shaft neck inclination

The invention discloses a method for calculating the mixed viscoelastic flow lubricating performance of a dynamic load bearing under the condition of shaft neck inclination, and solves the problem that when a dynamic load sliding bearing system is under the working condition of shaft neck inclination, a traditional method for calculating the mixed lubricating performance of the bearing neglects that the viscoelastic deformation effect of the bearing is obvious due to the fact that the load is greatly and rapidly changed. According to the method, the oil film cavitation and friction interface surface topography effect are comprehensively considered, a mass conservation average Reynolds equation is established, then the inclination state of the bearing is represented by adopting two shaft neck inclination angles in the horizontal and vertical directions, and the viscoelastic deformation of the bearing under the dynamic load action is calculated by utilizing a standard linear solid model.
