简介:锻模的三维造型是锻模CAD/CAM/CAE一体化的基础,但是锻模型腔的设计工艺参数(如拔模斜度、过渡圆角和分模面)常常可变,工艺形状所要求的光滑过渡的曲面数目也较多,因而增加了三维造型的复杂性。下文以DELCAM的POWERSHAPE软件为基础,介绍了汽车曲轴、连杆、转向节、前轴等的三维造型方法。
简介:建立一种有效修正相场模型来模拟小平面枝晶生长形貌。通过该模型分别研究网格大小、各向异性值、过饱和度及不同重对称性对小平面枝晶生长形貌的影响。结果表明,随着时间的推移,晶核生长为六重对称性的小平面形貌。当网格尺寸大于640×640时,小平面形貌不受模拟网格大小的影响。随着各向异性值的增加,小平面枝晶的尖端速度增大到一个饱和值后再逐渐降小。随着过饱和度的增加,晶核从一个圆形演化为发达的小平面枝晶形貌。根据Wulff理论和对应的小平面对称性模拟形貌图,证明所提出的模型是有效的,并能够拓展到任意重对称性的晶核生长的模拟。
