摘要

輪毂是車輛行駛中重要部件之一，發揮著承載汽車全身重量、車輛外觀、轉向和驅動等重要作用。隨著汽車工業朝向環保、舒適、安全、節能方向發展，汽車的輕量化設計顯得更重要，輪毂的性能的好壞直接影響到汽車的壽命、外觀、安全性和舒適性。鋁合金輪毂以其優美的外觀、高強度、散熱性較好、質量較輕、外觀多變化、安全性能佳、回收成本低之優點，能使汽車耗油量大幅下降，且熔點低，易於製成一體成型的的零件，減少零件數量，使得汽車研發與製造成本降低，基於以上因素，鋁合金輪毂已逐漸替代鋼製輪毂，因此鋁合金輪毂已在此競爭下被研發應用，成為高品位汽車標誌。
旋壓成形加工為一種先進的製造技術，逐漸的應用到汽車輪毂的製造和生產中，汽車輪毂旋壓過程是一個複雜的成形過程。為了研究汽車輪毂的旋壓成形，在對輪毂旋壓加工分析上，建立了符合實際的力學模型。利用有限元素分析軟體DEFORM-3D對6061鋁合金材料旋壓過程進行模擬分析，得到旋壓成形過程的應力應變分佈情況，分析了變形區域的金屬流動規律和塑性成形機理，為有效的制定成形加工、優化加工參數提供了依據。

Hub is one of the important parts in the vehicle; it supports the vehicle weight, appearance, such an important role in steering and driving. As the automobile industry a tendency towards eco-car, comfort, safety, and energy saving which meaning the light weight design of automobile is more important. The wheel hub has a direct impact on the performance of the car's lifetime, appearance, safety and comfort. The advantages of aluminum alloy wheels which is elegantly、highly strength, better heat dissipation, nature lightly, safely function and highly changeable external, less recycling cost all can drop the automobile oil consumption off. As the melting point is low which is easy to integrate all of the parts in the one and cover the parts quantities. It can reduce the automotive research and development and manufacturing cost. In view of the various factors, the aluminum alloy wheels have gradually replaced steel wheels. It symbolizes the high quality and also it’s widely used in the automotive industry.
Spinning forming process is a complex process for an advanced manufacturing technology that has gradually applied to manufacture and produce in the automobile hub. To study and assay the spin forming process on the wheel which establishes a realistic mechanical model. To simulate the spin process which using DEFORM-3D to analysis aluminum alloy material of 6061. To analyze the variable area according to the metal flowing and plastic forming in spin process of the stress distribution. The reference data in accordance with taking shape and optimization of processing effectively.
