我译的《冷锻斜齿轮卸压孔设计与模具弹性变形控制工艺指南》（四）Process Guideline for Relief‑Hole Design and Die Elastic Deformation Control in Cold Forging of Helical Gears原文：模拟结果表明，模具等效应力并不随减压孔直径的增大而呈线性变化，而是呈现先升后降的趋势。受曲率突变及金属流动受限的影响，齿根处的应力集中最为显著，属于危险区域。因此，在设计阶段，必须针对该特定部位进行严格的强度校核，并预留足够的安全裕度。译文：The simulation results show that die equivalent stress does not scale linearly with relief hole diameter; instead, it peaks and then drops. The stress concentration is most critical at the tooth root due to abrupt curvature changes and constrained metal flow. Accordingly, the design phase must prioritize rigorous strength checks and adequate safety margins for this specific region.
