基于simufact.forming软件的车轮旋压模拟分析

基于simufact.forming软件车轮旋压模拟仿真段小亮1,李光杰1(1.西模发特信息科技(上海)有限公司技术工程部,上海 200336)摘要:旋压轮毂具有重量轻、强度高、寿命长、表面光洁,机械加工余量少等优点。
而旋压工艺过程复杂,影响因素多,造成实际旋压加工中工艺参数和工装的选择和调试较为困难,本文采用理论结合实际对钢质重型卡车车轮及铝合金轿车车轮旋压工艺进行模拟分析,得出了旋压件的应力应变、厚度尺寸变化、旋压力变化情况,验证了工艺参数的准确性与工艺的可行性,仿真结果与实际有较好的相符性。
通过simufact.forming软件在旋压产品研制过程中的应用发现,仿真分析软件可以提前判断旋压工艺的可行性及合理性,为旋压产品的研制提供重要参考。

SimuFact.Forming 多工步连续分析设置详解

CAE联盟论坛精品讲座系列
SimuFact.Forming 多工步连续分析设置详解
主讲人 阿毅CAE联盟论坛—总版主
背景介绍:
目前进行锻压、挤压分析的4大主流的商用软件:Deform、Simufact.Forming(原MSC.SuperForge)、Forge、Qform中,都可以进行2D/3D分析,但是如果是多工步分析,Deform只能进行手动切换,就是算完第一步然后人工手动再调入第二步的模型,以此类推,如果是计算很慢,那么晚上没有人值班时,不得不停止计算,浪费了很多计算资源;Simufact.Forming在这一点上很好,有一个StageControl功能,可以非常方便的对多工步进行连续分析,在分析过程中,不再需要人工对模型进行处理,遇到大型计算时,能够有效利用晚上的时间,进行连续分析,非常实用;下面对其过程进行详细说明;
1.首先设置第一个分析工步(此处不再详细解释,与普通的单工步设置一致),设置完毕后;在Processes上点右键(Insert Process)增加分析工步,直至设置完毕,如有5步:
再设置第二步时,Worpiece只设置材料和温度条件;
2.所有的分析设置完毕后,在Processes上点右键,增加一个StageControl(Instert StageControl)功能;
然后拖动设置好的5个分析工步至StageControl下,如下图所示:
默认情况下,STEP1计算完毕后,会自动的将Workpiect工件自动的设置到STEP2中,如果还需要DIE,请在step2以下工步上点右键,选择所需要的模具
所有设置完毕后,在Stage Control上点右键,进行多工步计算;。

1. 创建一个新的工艺仿真
通过开始菜单或桌面快捷方式打开simufact.forming软件。
在软件界面点击File下拉菜单中的New Project,或者通过快捷键Ctrl+N来创建一个新的工艺仿真。
或者通过点击新建图标来创建一个新的工艺仿真。
点击后会弹出如下Process Properties对话框:
这里可以设置仿真相关参数:锻造类型(热/冷)、仿真类型(2D/3D)、和求解器(有限元/有限体积)。
当选择完工艺类型后,系统将自动定义相关参数。
下面可以选择模具数量。
操作步骤:
左侧选择工艺类型为Open Die(开式模锻),修改锻造类型为Hot
保留缺省设置(3D和FV)
点击ok确认
2. 仿真建模
确认后,你可以看到simufact.forming软件已经自动设置好了仿真所需要的相关参数。
在左侧可以看到仿真所需要的进程树,右侧为预览窗口。
鼠标左键缓慢双击要修改名称的进程树,或者通过右键单击选择Rename可以修改名称。
3 导入几何模型
导入模具和坯料的几何模型有两种方式:
1、在菜单栏点击Insert —Model —Form file/CAD import
2、下图所示第二个空白区(备品区)点击鼠标右键Model —Form file/CAD
import
解释:
Form file:一般导入通用有限元格式,如STL、BDF、DA T、ARC、T16、WRL 和DXF。
CAD import:可以直接打开proe、catia、ug、SolidWorks等默认格式文件,无需转换。
选择Form file导入STL格式文件,例子中要用到的文件我上传到附件中了。
在弹出的对话框中选中如下三个文件:Lower.stl、Billet.stl、Upper.stl,点击“打开”
选择单位为:mm
在备品区用鼠标左键拖动Lower、Billet、Upper到左侧进程树对应模具和坯料中
拖动后在右侧图形区会出现图示几何模型。
点击切换鼠标功能按钮,切换鼠标功能,点击按钮,将鼠标功能切换
为移动功能,点击,限定只能沿Z轴移动。
在进程树中选中upperdie(上模)。
在右侧图形区,按住鼠标左键拖动上模和下模分开。
拖拉完毕后,再次点击切换鼠标功能按钮,切换鼠标功能。
在进程树workpiece上点击鼠标右键选择Align BoundingBox。
在弹出的对话框中间选择LowerDie,意为:使坯料向下模以一定方式靠近。
点击上部和下部Center按钮,选择坯料和下模的参考点均为中心点,使坯料的中心点和下模的中心点重合。
点击ok。
点击切换鼠标功能按钮,切换鼠标功能,点击按钮,将鼠标功能切换
为移动功能,点击,限定只能沿Z轴移动。
在进程树中选中workpiece(坯料)。
在右侧图形区,按住鼠标左键拖动坯料至上模和下模中间位置。
同理,使用拖拉方式,将坯料限定在X方向移动,在进程树中选中上模,
点击工具栏透明图标,隐藏上模。
使其移动到如下图所示位置。
在进程树中选中workpiece,点击菜单栏Tools,在下拉菜单中选择Positioner。
在弹出的坯料位置自动确定对话框中,选择坯料自由下落方向为Z,点击向下的箭头。
坯料自动落到下模上面。
如图所示。
4 定义材料
模具材料的定义:如果不定义模具材料,缺省设置为H13模具钢,同样在备品区点击鼠标右键,出现如下图菜单,选择Material-Library
在材料数据库中选择Steel—DIN_1.7131 (16MnCrS5),点击Load,所选材料出现在右侧备品区。
点击Close关闭材料数据库对话框。
将备品区所选DIN_1.7131材料通过鼠标左键拖拽到左侧进程树Workpiece 下方。
5 定义压力机
右键在备品区单击,选择Press —Manual,弹出如下对话框,选择Crank press (曲柄压力机)并定义相关参数如下图所示:
然后将所定义的压力机press1在备品区通过鼠标拖拽到进程树中。
然后再将上模拖拽到press1下面
6 定义摩擦
在备品区点击鼠标右键,或者通过Insert —Friction —Manual插入摩擦类型,选择Coulomb Friction and Plastic Shear Friction,定义摩擦因子等相关参数图如下图所示,然后点击OK。
将定义好的摩擦通过鼠标拖拽到进程树中的上模和下模上。
如图
7 定义温度
在进程树中用鼠标左键双击Ambient Temperature设定温度为50℃。
在备品区点击右键或者点击菜单Insert —Heat —Die —Manual设置模具温度,相关参数设定如下:
同样Heat —WorkPiece设置坯料温度,相关设置如下:
将模具温度和坯料温度拖拽到左侧进程树对应处,如下图所示:
8 其它控制参数设置
点击菜单栏Tools,在下拉菜单中选择Define Point。
弹出定义点的对话框。
用鼠标在右侧图形区选中上模模面上的一点。
点击定义点对话框中的Add (添加下一点),在右侧图形区选中下模模面上一点,再点击Add,点击Close 退出。
在进程树中左键双击Forming,出现如下工艺过程相关参数定义对话框。
点击按钮,使用前面定义的两点确定压力机行程。
在弹出的对话框中,分别选择前面定义的两个点,在Distance at 100% stroke
处输入2。
意为:压力机达到最大行程时,两个点之间的距离,这里也就是上下模之间的距离。
点击ok返回。
其它设置采取默认设置,点击Start按钮可查看模具运动是否正确,如果正确,点击确定后退出。
在Element Sizes菜单中可以调整坯料在通过优先体积法计算时,单元的边长。
如下图所示,入选中Show FV in Pre,则在右侧图形区可以看到所划分外表面单元的大小。
下面两个图是分别选择单元尺寸为10和5时所划分的单元格对比。
在仿真中,我们根据实际需要选择单元大小。
