[Case Study] Improvement of Springback Accuracy in 1180MPa High Tensile Steel

We will introduce the evaluation results considering advanced friction models using TriboForm.

In the simulation study conducted at high tension, where issues are often observed, we will introduce a case that focused particularly on "friction" and worked on improving accuracy. With the goal of enhancing accuracy in the process (drawing die) and reducing lead time, we conducted calculations using AutoForm with two different friction conditions and compared the results with actual panel dimensions. In simulations using constant friction, phenomena that were excessively represented were confirmed to show behavior changes closer to actual panels by using the TriboForm model. This led to a reduction in lead time due to fewer modifications needed in die manufacturing. 【Key Points in Evaluation】 ■ Setting thresholds based on an understanding of the impact of friction (tribology) on quality ■ Establishing a feasible schedule aligned with the trial dates for evaluation ■ FV settings for AutoForm simulation (FV settings: parameter settings suitable for accuracy evaluation) ■ In-depth technical discussions on friction issues and sharing of concerns *For detailed information on the case, please refer to the related links.
