Hi at all.
Found a little bit time this morning.
My students are busy (I work as trainer for Solidworks) and I am not at home where we have some visitors over the Eastertime.
Here is an overlook about the workflow with MoI and Z88.
1. Drawing the framestructure in MoI (closer description will follow)
2. Editing of the z88i1.txt file (wirh the help of Max´s script; example next time) and save it in Z88
- we can see now the structure in Z88 with the labeling of the knots and the struts -
3. for different loads we make different files z88i2.txt (needs also a description)
4. we calculate every load in its own process
5. from Z88 we will get every time a file named z88o3.txt (here we have the tension and compression loads for the struts between the knots)
6. we take an excel sheet and put the inhold of the z88o3.txt in a column. After all calculations we have horizontaly all loadcases and verticaly
all struts. With an excel funtion we filter horizontaly all worst loads of tension and compression from our struts (max/min funktion)
7. As essence from all calculations we make a second excel sheet.
-Number of strut- startpoint (knot)- endpoint (knot)- true length- tension load- compression load- wall thickness- weight of strut
8. Now we calculate the outer diameter of our tubes (for this I have a little software in "dos" I would like to spend).
If the result shows Ø 14,58 we take Ø15 from our hardware dealer for example
9. Now we can draw the real structure
Every step will have later it´s own little tutorial with pictures.
In the first moment it seems a little bit complicated. But sometimes we have more then 200 struts an maybe 80 ore more knots in a 3D structure and
I had sometimes more then 30 loadcases. To calculate this needs many weeks. (If it is possible).
At next I try to test the script from Max.
Have a good time
Hans
