| 中文摘要 | 试开发了一套基于计算机辅助设计和数值模拟的空心铝型材挤压过程计算机仿真系统,它涵盖了模具工艺设计的全过程,可以集成原有的和新建立的工艺设计知识。该系统包括空心型材挤压模具及坯料的参数化几何造型模块,并能分析分流桥的截面形状、分流孔的布置、焊合室的高度、工作带长度和阻流或者助流结构对金属流速分布的影响,模具的弹性变形对工作带有效长度和模孔尺寸的影响。; A computer simulation system for hollow aluminum profile extrusion dies has been developed based on 3D CAD system and numerical simulation, which includes the whole course of die design technology and integrates the available and newly developed design knowledge. The parametrical modeling of workpiece and die for hollow profile extrusion model is implemented. The effects of leg-shape, porthole layout and dimensions, welding chamber height, bearing length dimensions and choked or relieved parts on metal flow are analyzed. The change of die opening dimensions near the bearing caused by the elastic deformation of die can be analyzed. |
