Numerical Simulation Method for Roll Forging and Forging Process of 7050 Aluminum Alloy Control Arm and Analysis of Final Forging Coarse Grain

摘要

In order to solve the problem of low production efficiency and low quality of product when machining the control arm of the free-form blank-die forging process, this paper adopts the roll forging-forging process and studies the grain size during the final forging process of the automotive control arm. Elemental software for numerical analysis, the analysis results show that the roll forging process can be processed with good mechanical properties of the control arm.
