摘要：针对商用铝合金轮毅法兰盘的站构特点对银造工艺及模具结构进行改进，将预锻过程中上，下模设计成波浪形，使材料在锻造过程中流动更加顺畅，终锻过程中材料的变形更加均匀，利用simufact软件对锻件的锻造工艺进行有限元模拟分析，并以模具温度、坏料温度、上模下压建度、摩赛固数4个工艺参数为固素，以成形载荷为目标函数，建立正交试验，确定最佳工艺参数，经验证，改进模具结构和
参数优化后锻压成形力降低了20%，为实际生产加工提供参考，关键词：铝合金轮毅；锻造工艺；模具改进：参数优化

Abstract: According to the structure characteristic of commercial aluminum alloy

hub, the forging process and die structure were improved. The upper and lower die in the pre-forging process were designed into wave-shaped, which could ensure the materi-al flow more smoothly in the forging process, and the material deformation in final forg-ing process was uniform. Then the simufact software was used to simulation analysis the forging process of

轮毅是汽车行驶中的安全部件，长时间在摩擦力大、高强度和高负荷的环境下工作。轮毅的轮辋和轮辐部位常因疲劳而出现破损、裂纹等缺陷叫。因此提高锻件力学性能以解决因疲劳引起的缺陷，轮毅成形工艺必须要考虑此问题。但是18英寸以上的商用大尺寸轮毅与小尺寸轮毅在成形工艺上有较大差别，小尺寸轮毅成形工艺为低压铸造、锻
