I am trying to calculate the number of pieces that would fill 1/2 of the volume of a cylinder, 9"dia x18"long. The parts are close to the shape and size of a bottle cap. Actual size is a bit larger. I searched here and the web without finding relevant discussion.

This job will run millions of parts a year, so a good close number without doing the over simplified "cyl volume/part volume" is required to find the number of stations we need. We only have one sample finished part so we can not just pour them in and count.

We have SolidWorks 2012 Premium and Simulation Professional.

Thanks

Perhaps this would be better handled in another section of this forum.

I am not sure SW can help you with this one...a hand calc seems like the way to go.

Considering there is an uncountable number of arrangements the parts could take, you'll have to simplify it in a way that gives a reasonable "packing factor" which will be a close approximation to the average number of parts that will occupy the volume. The way I would do it is assume the parts are stacked in discrete layers with all of the parts being oriented on the flat side (thinking bottle caps here) and touching one another. Calculate the ratio of the volume occupied to the total volume of that layer. This gives you a packing factor. Find the volume of half the cylinder. Multiply the packing factor by the half-cylinder volume to find total volume of the parts. Divide that by the volume of one part.

This actually comes out to the maximum number of parts that you could fit into the volume.
