[Abstract]:The tin bronze connecting rod bushing was numerically simulated by Deform-3D software. The temperature extrusion process of engine connecting rod bushing was simulated and analyzed by single factor process parameter test method and orthogonal test optimization test method. The friction coefficient and temperature extrusion speed were obtained. The influence of temperature and other parameters on the extrusion force and damage value in the process of warm extrusion is significant. By means of range analysis, two groups of optimal warm extrusion process parameters are obtained. By comparing the effects of two groups of optimal solutions on extrusion pressure and damage value, a group of optimal solutions, that is, friction coefficient of 0.1, is obtained. The temperature extrusion temperature is 700 鈩，
