Optimization of texture shape based on Genetic Algorithm under unidirectional sliding

A numerical approach was proposed for the optimization of shape contour of recessed surface texture under unidirectional sliding. The approach was developed based on a Genetic Algorithm to improve the tribological performance. Results indicated either bullet or fish shape to be the preferable texture shape contours. Analyses on the hydrodynamic pressure distribution suggested that the increase in hydrodynamic upthrust of the obtained textures...
