Hi again,
sorry for posting again so late, but there were quite a few things to be done ...
So here what it is all about:
I've created a Excel-file with many different sheets within to do the following:
-1- define the input-values like
+ setcions of a shaft (diameter, length)
+ material paramters (mechanical stiffness parameters)
+ the points where loads are aplied to the shaft as well as the mounting points
+ ....
-2- the sheet is built up in the way that the reaction forces at the mounting points are calculated automatically by value (not by formula)
-3- on another sheet ...
+ the internal force variables
+ the single mechanical stresses (like tensile stress / pressure, bending stresses and torsional stress) are evaluated by combining the internal forces with the given geometry data
+ the reliability is determined from the given stresses and the material parameters
All this is calculated by value (not by formula) in a veeeery huge table
3-numerical_calculations.jpg (1,005kb) downloaded 9 time(s).-4- the results are shown in some diagrams
Often I need to write a sample solution. For this I need to document the way how to get to the solution by formula (and not as it is done within the Excel-sheets by value only (yes there are fomulas too within the sheets but they are generated in a veeeery general way, so nothing ever any engineer would use without a computer).
For this reason there is
-5- a sheet where it is possible to generate some free punches for calculating
+ the reaction forces and
+ the internal force variables
5a-preparing _data_for_free_punch_output.jpg (824kb) downloaded 14 time(s).Because this is just a "static" picture [as it is not possible to build a 3D-vector-diagram wihtin Excel] I thought about using Geogebra so there is
-6- another sheet where the given model (shaft-geometry, loads, reaction forces and if needed the inernal forces) is translated into text-command-lines to be used as an input on Geoegebra's input line.
Maybe you can - by looking at the screenshots - follw my decision to use Excel-sheet instead of the sheet-functionallety within SMath...
Now, at least, the only thing for documentation which is still missing is generating the the formulars for calculating the reaction forces and the internal forces, and maybe somewhen the stresses and the reliability at certain points.
.... and all this was leading to the question: Is there a way to import commands, which are given in a text-form (e.g. F.Ax:100'N <CR> F.Bx:F.Ax-F.Sx=), into SMath. Or is there any way to write my own .sm-file or any other way the get those commands into SMath-sheet?
I hope posting a screenshot of every given point is helping to follow my explanation.
So and after this I hope what I'm trying to find and can help me out with some solution ;-)
Regards
