Influence of Geometrical Shape on the Lubrication Performance of Partially Micro-Grooved Gas-Lubricated Parallel Slider Bearings

The influence of grooving parameters and micro-groove cross-section shape on the lubrication performance partially micro-grooved gas-lubricated parallel slider bearings is investigated in present study. solution procedure for multi-grid finite element method that algebraic equations formed by are turn smoothed interpolation from coarse grid to fine restriction grid. By adopting method, pressure distribution obtained. optimized obtain maximum average different shapes. results show orientation angle micro-grooves, depth width area density fraction, micro-grooves have an important hydrodynamic bearings. this study demonstrate can be obviously enhanced appropriate cross-shape. beneficial design
