模型修改完毕，有如下几点说明一下：
1：如果你的模型，上下两块在整个过程中如果没有发生时而分离，时而接触的话，我建议还是不要做接触，如果做了接触，而你在竖直方向没有约束，上面的部件很容易被下面的部件“弹开”，这与实际情况并不符，所以，我直接把上下两个部件做了共节点。当然，你也可以做接触，但需要另外加约束，这也是你之前那个模型很难收敛的主因。
2：你的材料属性里面涉及弹模，热膨胀系数等参数，应该是做结构-热耦合分析，而不是单纯的热分析，我已经帮你改过来了。
3：根据你的边界条件，我判断你的模型是轴对称的，而不是平面应变模型（这是我的猜测，也可能不是），如果我的猜测的是对的，你还要把模型改为轴对称的。

修改的模型见附件：

汗，我传不了附件了，估计是之前传得太多，受限了，我把inp贴出来：

你好，你给的建议很好。我做的确实是轴对称的温度-结构耦合分析，但我想先做温度分析，得到结果看看，因为在第二步热应力分析时我还需要加上一个冲击力，也就是说第一步我用热分析，第二步再用温度-位移耦合分析。你分析很有道理，应该是接触出了问题，也就是说热分析时我不需要加接触吗？

对不起，我刚学的ABAQUS，inp格式的还不是很熟悉，你真的没办法传CAE文件吗？

我发到你邮箱吧，将上面的内容拷贝到记书本中，同时将记事本后缀改为inp，就可以导入aba中计算了。

好的，实在太感谢了，tingting88912@yahoo.cn

你最好都用结构-热耦合分析，一样可以模拟出你想要的温度，否则，接触那块就会出现很多问题，我也给你算过接触的情况，是在结构-热耦合分析中做的，你一定要按照实际模型来选择合理的计算模型，否则，结果会让你很“尴尬”。

但是那样我选的单元和边界什么的都需要改啊

北鹰南飞 · 发表于 2011-5-29 15:38:03

做CAE分析本就是件繁琐的工作，，，

你给我传的版本比我机上的高，还打不开

。你是如何设置共节点的呢？
