Hydraulic/pneumatic paradigm shift

[Michael0456]

TL;DR

Hi all.

To begin, we all know that in a typical cylinder for example, the pressurized area inside the barrel far exceeds the axial. Actually, once the stroke of a cylinder exceeds 1/4 the diameter, the radial (wasted) forces equal the linear ('used') forces generated.

Subsequently, I had the idea to keep cylinder ends stationary, and to find some ways to expand the cylinder wall so to speak.

I have done some preliminary work in this area, and in looking at what happens to the volume of fluid itself reveals quite a few incredible things, and opens up a very large rabbit hole in actuator design, pump design, even to propulsion & combustion chambers & the like.

Anyway, I began an article for a cylinder that emulates a muscle (as I see them functioning anyway), but this change in paradigm sent me on too many tangents.

Subsequently, please bear in mind the article is unfinished (is Pt 1), and is an incomplete rough draft. It's also just in wordpad, a simple program on a simple computer. please forgive any errors in presentation.

I hope you find the concepts as interesting as I did. This article is free issue.

be well all, happy designing :)

lol, it ends up a simple 'wordpad' file isn't supported. If you would like a copy of a preliminary article, please message me or tell me how to get around this haha

Welcome to the PF.

For right now, your thread is in the Moderation Que awaiting approval. We need to see the file before we can decide if this is a valid thread start or not (we don't allow personal theory development here, but if it's just a question about the efficiency of a different sort of mechanism, we may be able to allow it).

Please use a free PDF writer (like PrimoPDF) to print your WordPad file as a PDF and attach it to a reply here. I'll have a look to see what we can do.

Thanks.

Just one preliminary comment: "Wasted forces" isn't a thing. A force against an object that doesn't move just does nothing in a hydraulic system. It doesn't matter.
