标题: 每日一问！（4）
老大帮我看看，这个热成形设置好了以后要运行的时候出现的问题，图在下面

作者: zoe122208 时间: 2009-9-8 18:08
*** ERROR *** ISOTHERMAL CALCULATION:
IMPOSSIBLE TO IMPOSE TEMPERATURE
运算以后出现这个，是不是温度没有导进来，怎么样才能导进来温度呢

作者: yanstill 时间: 2009-9-8 19:16
gravity下设置了温度了吗?

作者: zoe122208 时间: 2009-9-9 09:03
设置了，凸模120 凹模120 压边圈25 板料860

作者: kofkiller 时间: 2009-9-9 09:42
这个多工序？忘了设PICKING属性了？？

作者: yanstill 时间: 2009-9-9 20:01
把重力过程下的温度去掉,软件中重力过程是不考虑温度的

作者: zoe122208 时间: 2009-9-9 22:17
谢谢斑竹！

作者: zoe122208 时间: 2009-9-11 12:55
还是有问题，如果不设置温度，就说重力过程必须设置温度，我采用picking的方式以后还是说Gravity will be isothermal 运算出现下面这些，老大帮帮忙。

作者: yanstill 时间: 2009-9-11 22:50
1.重力过程需给blank设置一个初始温度(initial temperature)
2.压边阶段不能用picking(即只能重新给一个温度边界条件,也就是不考虑重力阶段的温度)
3.拉延阶段要使用picking

1.重力阶段给不给punch和die还有blank holder温度呢？
2.压边过程是不是这几个都要设置？
3.冲压过程只picking就行了吗？不用设置温度了吗？

作者: yanstill 时间: 2009-9-15 15:45
kofkiller 工作太努力了...

压边过程不能用picking,所以要设置温度，冲压过程已经用picking了,所以不用设

热成形计算会比一般的冷冲压慢的,多了边界条件

为什么HOLDING不能用PICKING呢？？

作者: zoe122208 时间: 2009-9-17 11:38

那重力阶段用不用设置压边圈和凸凹模具的温度呢？谢谢版主啊，你真是个大牛！

那就好，肠胃不好少吃辣，我也喜欢吃辣，呵呵

作者: yanstill 时间: 2009-9-17 22:57
重力阶段需要加温度，但实际不起作用，所以holding那里不能picking,这是内部算法的原因,以后可能会改吧
