本文讨论了钛板成形过程中存在的一些工艺问题，如拉深性能差、易产生粘扣、回弹等。采用基于有限元法的Adina System v.8.3对冲压成形过程进行了数值模拟。分析了摩擦力、压紧力和模具几何形状对冲压过程的影响。计算所需的机械和工艺材料数据通过实验确定。通过“拉带”试验确定了不同润滑剂和防粘层的“钛-工具钢”摩擦副的摩擦系数，指出了润滑层和防粘层在防止钛在工具上“堆积”方面所起的作用。计算结果得到了实验验证。
In this paper, some technological problems (e.g. low drawability, high susceptibility to galling, spring-back) occurring in the sheet-titanium forming process are discussed. A numerical simulation of the stamping process was carried out with the Adina System v.8.3 based on the finite element method. The effects of friction, the holding-down force and tool geometry on the course of the stamping process were analysed. The mechanical and technological material data needed for the calculations were determined experimentally. The friction coefficients for the frictional pair: ”titanium – tool steel” for different lubricants and antiadhesive layers determined in the “strip drawing” test were found. The role played by lubrication and antiadhesive layers in preventing titanium “build-ups” on the tools is presented. The calculated results were then confirmed experimentally.
