In order to optimize the forging process of mechanical connecting rod and improve the mechanical properties and wear resistance of mechanical connecting rod forgings, the forging process of mechanical connecting rod with aluminum matrix composites was controlled by conventional PID control and fuzzy PID control, and their mechanical properties at room temperature and wear resistance under the two methods were tested and analyzed. The results show that compared with the conventional PID control, the tensile strength and yield strength of the connecting rod produced by the fuzzy PID control increase by 36 MPa and 45 MPa respectively, and the wear volume after wear test for 20 minutes decreases by 42.3%. Furthermore, the fuzzy PID control method is significantly better than conventional PID control. Thus, the mechanical properties and wear resistance of the forged mechanical connecting rod produced by fuzzy PID control are better than that by conventional PID control, which is beneficial to the improvement of comprehensive performance of forged mechanical connecting rod.
