glide 活塞刚度矩阵无法读入

rlm2020 · 发表于 2010-3-24 15:18:41

如题。我照着例子做。刚度矩阵是直接把mono128例子里面的刚度矩阵文件复制过来的。可是check的时候出来下面这段话。请问各位大侠这是什么原因？

Starting Pre-Processing...
TASK: Check Stiffness ...
Glide Pistonslap control parameters not registered!
*** Error in Pre-Processing Task "Check Stiffness"!
finished Pre-Processing

Calculation cannot be started.

是不是刚度矩阵定义的活塞高度，超过了你定义的活塞高度

rlm2020 · 发表于 2010-3-26 10:19:02

没有的，我是完全按照例子往里输的

rlm2020 · 发表于 2010-3-26 16:59:48

另外我自己写的一个刚度矩阵文件导进去的时候提示错误

=== FATAL ERROR ===                                     (MODULE: STIFF_READ)
READING BLOCK    NODEPOS
UNKNOWN KEYWORD NODESTIFF
IN LINE          33

不知道是什么意思，例题的刚度矩阵文件里面也有这个关键字啊NODESTIFF

另将刚度矩阵文件导上来，请各位大侠帮忙看看有什么问题。

sym 0 改成 sym 1
nmer 4 改成 nmer 3

谢谢小熊。果然可以了
不过又有新错误，系统提示异常刚度矩阵。

rlm2020 · 发表于 2010-3-27 18:06:30

还有几行说我尺寸有问题，我想问一下，在求刚度矩阵的时候是必须取活塞最高点和最低点吗？

xiaoxiong0721 · 发表于 2010-3-27 19:31:41

不要取活塞最高点和最低点，力要加载在一个小区域里，最高点最低点不能代表这个区域的平均刚度水平。

rlm2020 · 发表于 2010-3-28 22:51:00

那我这个错误提示是什么呢？刚度矩阵搞了好长时间了，一直没能搞出来
刚开始的时候看教程觉得挺简单的，后来真正做的时候一直出错
我是这样做的：
在活塞上取了3排一共17个点，在每个点上加径向载荷1000N（顶上和两对称面上的约束和教程一样），然后建了17个工况，每个工况对应一个载荷。在计算的时候只输出这17个节点的位移值（全输出的话f06文件太大打不开）。然后将这17个工况一起计算
在f06文件里读取位移值填入刚度矩阵文件（就成了我上面贴出来的文件）
不知道我错在哪里了，计算不了
小熊能帮我看看吗？

蓝：最好这样。否则就要外插了。
