摘要对钛合金粉末热等静压成形叶轮盘进行数值模拟分析,研究其等效塑性应变分布和节点密度随时间的变化规律,以及压制件相对密度分布规律,并采用热等静压技术制备叶轮盘样件。结果表明：数值模拟结果与实验数据呈现较好的一致性。这一发现充分证明了数值模拟技术在叶轮盘热等静压工艺过程中的有效性,以及预测成形特性的准确性。这不仅为优化叶轮盘的生产工艺提供了有力的数据支持,也为后续复杂零件的成形预测奠定了坚实基础。

Abstract：Numerical simulation analysis was conducted on the hot isostatic pressing of titanium alloy powder to form impeller discs. The distribution of equivalent plastic strain and the variation of node density over time, as well as the distribution of relative density of pressed parts were studied, and impeller disc samples were prepared using hot isostatic pressing technology. The results show that the numerical simulation results show good consistency with the experimental data. This discovery fully demonstrates the effectiveness of numerical simulation technology in the hot isostatic pressing process of impeller discs, and the accuracy of predicting the forming characteristics. This not only provides strong data support for optimizing the production process of impeller discs, but also lays a solid foundation for the subsequent prediction of complex parts.

Key words： hot isostatic pressing impeller disc numerical simulation titanium alloy plastic strain
