We have published a CAE case study titled 'Optimal Method Analysis Using CAE with Double Action Press | Realizing High-Speed Consideration for Two-Stage Helical Gear Forging'.
Are you facing such walls when trying to examine complex shape forging processes with CAE?
- The computation time is enormous, making it difficult to cycle through PDCA.
- Spending several days just to set conditions.
- Ultimately, the results do not match the actual machine behavior and cannot be fully utilized.
Especially for difficult shapes like two-stage helical gears, the "computation cost barrier" from 360° full model analysis becomes a significant obstacle.
In this article, we will reveal the efficient analysis process utilizing "sparse gear segmented model (90°) × DEFORM" practiced by Yamanaka Gokin. First, we will use a fast segmented model to get a preliminary assessment, and then conduct full model verification in the final stage. We will provide a detailed explanation of a method that truly helps in practice, achieving a balance between computation cost and accuracy.
