Abstract：

Rocker arm is regarded as the key mechanical components of a hydraulic loader, which often appears crack because of the long working time and high intensity. In order to prolong the working life, ensure safety and enhance reliability of the loader, the rocker arm was produced by forging instead of casting based on the advantages of high intensity of forging. The forging process was formulated according to the shape structure of the large hydraulic loader forging rocker arm. Then, the forging process was carried out by Deform-3D, and simulation results of the stress，strain, temperature field, and the stroke-load curve in the rocker arm forging process were researched. Furthermore, the rocker arm was produced by forging hammer. The results show that the results of production experiment and the simulation are matched with each other. Simulation analysis provides a theoretical reference for the improvement of the forming process and optimization.
