Numerical simulation study on the quenching temperature and stress field of automotive transmission gear

In the field of automobile manufacturing, the precision and stability of transmission gears are crucial to the performance of automobiles. To investigate the changes in gear temperature and stress during quenching processes, this article established a model of automotive transmission gears. Subsequently, using the import function of the ANSYS software, the gear 3D model established in SolidWorks was imported and subjected to numerical simulation analysis. ANSYS, with its powerful simulation ability, can simulate the complex physical phenomena of gears during quenching and cooling processes, thereby obtaining temperature and stress distribution data of gears. These data not only help to understand the deformation and cracking mechanisms of gears during quenching and cooling, but also provide a key basis for optimizing gear manufacturing processes. When the parameters of the quenching process are reasonably adjusted, the risk of deformation and cracking of the gears can be effectively reduced and the accuracy and service life of the gears can be improved. In addition, this research method also provides the possibility of reducing the production cost of automotive transmission gears. Through numerical simulation, gear performance can be predicted and optimized during the product design phase, reducing the number of trial productions and production costs.
