| 摘 要： | 采用有限元法对带内环向加强筋铝镁钪合金筒形件旋压成形进行了数值模拟,分析了坯料应力应变分布状态和工艺参数对成形的影响.结果表明,轴截面坯料主要处于轴向伸长、径向压缩状态,内表面坯料处于轴向伸长状态；减薄率和进给比对成形影响显著,模拟分析减薄率不宜大于50％,进给比为0.5～2.0mm/r较佳.

| Abstract: | The spinning process for Al-Mg-Sc alloy cylinder with the inner circumferential rib is simulated by the means of FEM numerical simulation,the stress-strain status of the raw material and influence of technological parameter on spinning are analyzed.The results show the material is extended in axial direction and compressed in radial direction,and the material in the inner surface is extended in axial direction.Deformation ratio and feed ratio can influence spinning process,deformation ratio ought to be smal... |
