Comment on Shape optimized spoolholder
beeng@discuss.tchncs.de 5 months agoMore than likely the static supports used in the software were in the locations you see now,1 for spool and other’s bellow on the rail. If the static loads were placed at even height you would end up more triangle like or more of a truss. Depends shown many iterations were used also.

In a broader picture: See it as a demonstration of what all those nice tools in the CAD package can do. In this application with a little bit of thought could come up with a similar or better solution but for an I don’t care design approach the output is already good. A proper design approach would be putting thought in in where to place the contact surfaces relative to the spool and then run this software or go a step further and allow a different software to also change that parameter. Keep in mind those simulations are computationally expensive. Complex/advanced questions might take days to solve while a simple question like this is less than 1 minute.
The load was in the circle/groove facing down.
The other constrain was the faces contacting the 3030 extrusion being fixed and a keep-out zone was defined around those to ensure no material there was removed.
Otherwise, it was just a flat slab as shape.
What at first surprised me was how this part works: There is a point defined by the lowest/left triangle (tension & compression) on which all the weight rests. The remaining structure is is a cross beam (top mounting point to spool) to support it (tension) and the structure on which the spool rests (compression).
