| Title | Characteristics Analysis of Hydrostatic Bearing with capillary Restrictions |
||
| Keyword | |||
| Abstract | This study is primarily focusing on the influences of hydrostatic radial bearing on load capacity and static stiffness with different parameters, including number of recess, restriction, recess length ratio, and displacement ratio in capillary restriction. We constructed the flow continuity equations for each recess using Flow Resistance Network (FRN) method, solved the set of equations for pressure ratios, and then further obtained the load capacities and static stiffness. The FRN method establishes the flow rates and interactions within themselves in a multi-recess system based on energy equations. The rates are proportional to the pressure difference between two recesses, but inversely proportional to the flow resistance. The simulation results indicate that the hydrostatic radial bearing of capillary compensator has better performance with increase in the numbers of recess and decrease in recess length ratio. The stiffness is optimized with smaller restriction parameters under heavy load capacity. Moreover, while the number of recess is fixed and displacement ratio is greater than 0.3, the stiffness reaches its optimum with smaller recess length ratio and appropriate restriction parameters. |
