| Summary: | 碩士 === 國立成功大學 === 機械工程學系碩博士班 === 95 === In this research, finite element analysis method is used to simulate the multi-stage deep drawing processes of a connecting component, i.e. loudspeaker terminal. Based on tensile test, the material properties of copper C2680 with 0.5mm in thickness and the shell elements for elasto-plastic analysis method are used for the finite element simulations. The simulation result of the distribution of wall thickness was compared with the strip of the product manufactured by an existing progressive die. In addition, Taguchi method has been used to compare the influences of control factors based on the maximum thinning ratio as the quality characteristic. Four control factors are considered in this study; they are punch radius, die radius, lubricant and the clearance of die. The result showed that die radius is the most important influence factor in deep drawing process, followed by punch radius, clearance of the die and lubrication. The simulation model proposed in this thesis can be used for the design of the drawing process of a progressive die for a copper sheet component.
