【文章內容簡介】 conds ? Second operation: Fe to shape. 基本工藝 Creating a New Problem ? 建立一個新的 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)造對稱邊界條件和熱交換面，注意，對稱面不是熱交換面。 Defining Billet Temperature ? 將 billet的溫度設為 1230176。 C. ? 工具的溫度設為 80176。 C. ? 引進 DINC15材料數(shù)據(jù) (Steel category). Setting Top Die Movement ? 零件使用 mechanical press 成形 ? 設備能力 行程為 270mm ? speed of 85 strokes/minute ? ( strokes/sec). ? 整個成形行程為 billet的現(xiàn)有高度 (67mm) 減去 billet 的最終高度 (), 也就是. ? Also, this press has a co
