【摘要】 运用有限元分析软件PLOYFLOW对螺旋芯棒机头流场进行模拟计算,提出轴流周向角的概念,将其作为衡量机头混合性能的指标,用正交设计方法对结果进行分析,得出了机头几何参数芯棒锥角、螺旋消退角、螺旋升角和螺槽深度对机头混合性能的影响,并对机头参数进行优化,得到机头设计的最优几何参数组合。更多还原

【Abstract】 By using finite element analysis software POLYFLOW, spiral core rod die flow field simulations have made; proposed the concept of axial flow circumferential angle as the target of the mix performance of die. Through analyzing the result with the orthogonal design method, the influence of the mix performance of die by the die geometry parameter, such as core rod cone angle, spiral subsidising angle, spiral rise angle and the depth of helical groove had been obtained, and optimized the die parameter to get the most superior geometry parameter combination for the die design.更多还原
