Performance 另一方面 Simulation Tools 19731985的賓士車 特色 :Front Fender很長 十二年的期間 19851995的賓士車 特色 :Front Fender 變短了 十年的期間 為什麼呢 ? Because these times are products development times so , the front fender shortened dramatically 19952023的賓士車 特色 :Front Fender 的長度沒有太大的變化 七年的期間 再看一次 ! 19851995這十年期間的賓士車 比較 19851995和 19952023的賓士車 為什麼 Front Fender 沒有明顯的變化 ? 1. New materials development time not reduced significantly 2. Barrier to achieving optimum final product performance 另外開一條路 :simulation tools Casting of AZ31 ? AZ31:Mg alloy with three percent Al,1 percent Zn with UTS =260MPa and YS =200MPa ? Liquids:903K ? Solidus:878K ? C:1J/ with constant pressure Simulation of Extrusion Process with FORM Data needed: 1. Geometries 2. Materials data Such as specific heat ,conductivity(function of temperature) Parameters: Friction model?Heat transfer? 應(yīng)變模擬 最大主軸 (Principle Axis)應(yīng)力模擬 Crashworthiness Collision test with v=7(km/s) Carriage weight 830 kg 真實(shí)的情況 Designing materials:Computer . Laboratory? 1. DC casting of AZ31 2. New Design and Extrusion 3. Crashworthiness COMPUTER TOOLS AND EXPERIMENTS Conclusions: 謝謝 ! 謝謝觀看 /歡迎下載 BY FAITH I MEAN A VISION OF GOOD ONE CHERISHES AND THE ENTHUSIASM THAT PUSHES ONE TO SEEK ITS FULFILLMENT REGARDLESS OF OBSTACLES.
