中文摘要:针对阶梯轴的特点,应用QFORM软件对不同成形工艺方案下金属流动情况进行数值模拟,分析了阶梯轴在挤压成形中的载荷、应变的分布状态。针对阶梯轴在正反挤压过程中坯料的应力分布和速度场分布,分析、确定了最优的工艺方案。
英文摘要:Aiming at stepped shaft characteristics, utilizing QFORM software, the metal flow under different forming processes was numerically simulated, and the distribution state of load and strain of the stepped shaft in the extrusion was analyzed. Based on the stress distribution and velocity field distribution of stepped shaft billet in the positive and negative extrusion, the optimal process plan was definited.
