【正文】 high ? Material（材料） : DIN C35 ? Preheat（預(yù)熱） : 1230C ? Tool Temperature（模具溫度） : 80C ? Transfer from furnace: 7 seconds ? Dwell on die: seconds ? First operation: Flat upset to ? Transfer to 2nd tool: 3 seconds ? Second operation: Fe to shape. 基本工藝 Creating a New Problem ? 建立一個(gè)新的 Problem called Gear_Carrier. ? Simulation Title: Gear Carrier ? Operation Name: Furnace Transfer ? Operation Number: 1 ? Only Heat Transfer activated ? SI unit system ? Loading Object Geometry ? Workpiece: ? Top Die: ? Bottom Die: ? Workpiece is plastic, tools are rigid. Defining Workpiece Mesh ? Set the Weighting factors to: ? Surface Curvature ? Temperature ? Strain Distribution ? Strain Rate Distribution ? Mesh the billet using absolute mesh with a Max Element ? Size of 1mm and a Size Ratio of 1. ? 初始網(wǎng)格生成以后 將 the Size Ratio 改為 3, 不過不要再生成網(wǎng)格 . The program will use these new settings any time the billet remeshes during thesimulation which will allow more definition for the deformed billet geometry. ? (Size Ratio = 3, Min Size = .33mm, Max Size = 1mm) Defining Billet Boundary Conditions ? 創(chuàng)造對(duì)稱邊界條件和熱交換面，注意，對(duì)稱面不是熱交換面。 C. ? 工具的溫度設(shè)為 80176。 ? 現(xiàn)在工件已經(jīng)放在模具上面所以需要設(shè)定接觸條件。 ? 利用下拉菜單選擇 Free resting 值 (1 in SI units) ? billet/bottom die 之間的熱傳導(dǎo)系數(shù)也
