Abstract

This paper uses finite element analysis to analyze the changes in mechanical properties and micro structural characteristics of vehicle timing belt pulleys, which is a key component of vehicles engines, made using powder forging processes. The timing belt pulley is an important part that transfers the power generated by the engine to the drive shaft of the valve. The process happens as follows: The powder is inserted into a forging mold, and the product is formed from compression and finally sinter heat-treated in a high-temperature heat treatment furnace. This study aims to perform 3D modeling to analyze the forging process at each stage, then predict the changes in mechanical properties of the product in the subsequent heat treatment process through numerical analysis. The results of analysis will give the load upon the mold punch, product density, temperature distribution and stress and deformation distributions as the result of stroke changes during forging. Next, structural change and temperature distribution according to cooling rate will be found for various individual cross sections following the heat treatment process. The results will allow testing the effectiveness of powder forging process analysis.
