Methodology of physical modeling of sliding bearings
Annotatsiya
A new method is proposed to calculate sliding bearings considering geometrical and operational parameters of the test model. It is shown that the use of the initial condition of the infinite length of a hydrodynamic sliding bearing at pressurized lubrication is ungrounded since it does not take into consideration flow regimes of the lubricant at the inlet and outlet. To reproduce real operation regimes of hydrodynamic sliding bearings in physical models it is advisable to apply the principle of similarity by the Sommerfeld and Reynolds numbers. It is shown that the proposed method can be implemented with standard friction machines to determine experimentally and optimize the geometrical and operational parameters of hydrodynamic sliding bearings in order to improve their designs more reasonably.
