摘　　要：以轨道车辆用某一扁宽、薄壁、空心、弧形大型铝合金型材为研究对象,根据该型材特点制定模具设计方案,采用基于ALE算法的HyperXtrude挤压模拟分析软件对模具挤压过程进行模拟,将数值模拟结果与实际挤压结果进行对比,发现数值模拟结果与生产试模结果吻合。得出的数值模拟结果可以为大型复杂截面铝型材挤压模具结构设计和优化提供指导。A large aluminum alloy profile for rail vehicle is taken as the research object,which is flat,wide,thin-walled,hollow and curved.The mold design scheme is made according to the profile characteristics and the extrusion process was simulated by HyperXtrude extrusion simulation analysis software based on ALE algorithm.By comparing the numerical simulation results with the actual extrusion results,it is found that the numerical simulation results are consistent with the production test results.The numerical simulation results can provide guidance for the structural design and optimization of large and complex aluminum extrusion dies.
