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》（二）Process Guideline for Relief‑Hole Design and Die Elastic Deformation Control in Cold Forging of Helical Gears原文：为深入揭示卸压孔参数对模具受力与变形的影响规律，可建立三维、两步耦合模拟的有限元分析模型。该模型能够同时考虑坯料的塑性大变形行为与模具结构的弹性响应，从而真实再现冷锻过程中的应力传递路径与变形特征。通过设定不同的卸压孔初始直径工况，可以定量考察其对模具弹性变形特性的影响，为模具结构优化提供可靠依据。译文：To gain deeper insight into how relief‑hole parameters affect die loading and deformation, a three‑dimensional, two‑step coupled finite element model can be developed. This model simultaneously accounts for the large plastic deformation of the billet and the elastic response of the die structure, realistically reproducing stress transfer paths and deformation features during cold forging. By defining different initial relief‑hole diameters as simulation cases, their quantitative influence on die elastic deformation characteristics can be investigated, providing a reliable basis for die structural optimization.
