| 摘 要： | 建立了汽车轮毂端盖拉伸成形三维弹塑性有限元模型,并利用MARC软件对其拉伸变形过程进行了数值模拟。分析了金属材料在拉伸成形时的流动及拉伸成形后的残留应力和应变分布情况,研究了凸模圆角半径对板料成形性能的影响及防止产生起皱与破裂的措施。研究结果表明,当凸模圆角半径值小于2~3倍料厚时,材料易产生拉裂现象。模拟结果与实际生产吻合较好,说明所建立的有限元模型是合理的。

| Abstract: | The 3D elastic-plastic finite element model for the stretch forming of automobile wheel hub end housing was established, and the deep drawing process was numerically simulated by MARC software. It mainly focused on the analysis of the flowing of metal materials during deep drawing and the distribution of residual stress and strain after deep drawing. The influence of the corner radius of punch on the performance of the sheet metal forming, and the measures to prevent the wrinkling and breaking off of the drawn work piece were also researched. It showed that when the corner radius of punch is less than two to three times of blank thickness, drawing crack might occur. The simulation results conformed well to the practice ones. It indicated that the finite element model established in this paper was appropriate. |
