Application of numerical simulation technology in gear forging

Before the 1990s, the research and production practice of gear forging was mainly based on physical simulation. That is because the numerical simulation method at that time was not perfect in simulating plastic deformation, and was not ideal in predicting metal deformation law and accurately calculating parameters such as...
