| description | The application of surface texture technology can cut down the friction of journal bearing in internal combustion engines, so as to reduce energy consumption and improve effective. A three-dimensional simulation model of the lubrication characteristics is established so as to investigate the effect of surface texture on the load capacity of journal bearing. The accuracy of the simulation model is verified by comparing with the test. On this basis, through the establishment of a two-dimensional texture unit lubrication characteristics simulation model, the influence law of four different texture shapes, such as triangle, arc, rectangle and trapezoid, and typical structural parameters on the load capacity of the load capacity is studied. Finally, a three-dimensional simulation model of lubrication characteristics of the rectangular textured journal bearing is established. Based on this model, the effect of texture distribution position on the load capacity is studied. It shows that the position of the texture will affect the load capacity. The maximum pressure and load capacity are increased when the texture is in the wedge gap convergence region, but they will decrease when in the divergence region. |
