Hydraulic Cylinders

[Flavioborges]

I would like to test a good software to calculate hydraulic cylinders. Anyone could help me?

What kind of information are you needing?
We use MathCad, Excel, SolidWorks, CosmosWorks and CosmosMotion for design. Each package provides different information.

I need to know how to make a hydraulic cylinders, i mean, i am not a fluid expert, so i need a software that makes my job easier

There are many reasons for different hydraulic cylinder designs. There is no software that I know of that will evaluate how to design hydraulic cylinders. The learning curve of designing cylinders will be hard to justify if you can purchase what you need from some one who already designs and manufactures them.
We build heavy duty cylinders for industrial, forestry and construction, but if an off shelf cylinder will work, we purchase them because our cost to manufacture them is more. If a cylinder lasts less than a year or 2,000 hours then we look at the application, the cause of failure, and see if one of our standard designs will work. We have a US patent on a high pressure piston seal developed for working pressures of 7,000 psi and will take spikes to 20,000 psi, for logging grapples, clam buckets, and thumbs for excavators. The design and testing of the grapple and clam bucket cylinder took several years and several iterations before success. The thumb cylinder test machine cost a lot, it had a 14” bore cylinder to apply work induced loads, up to 460,000 lbs so we could identify what caused certain failures.
If you have no choice but to design and manufacture cylinders, good luck.

On the other hand, we purchased micro hone tubing, had rods machined inhouse then sent to local chrome plater, which cost us much less. Your force and speed are pretty straightforward. Incorporating applicable mounting styles is key to success, and I don't believe there's much for software in that area.

I guess what you need may be those software that will help you to size the cylinder as per your application, am i? If you only need this type of software then I will be much easier; but if you need software that they teach you how to make the cylinder, in the sence of telling you the piston size or may be how many seal that have to use and where to put the seal, then I think this will be much much more impossible to have this software, I guess.

Parker Hydraulics sells software but I think it for complete system. They also sell a Fluid Power Design Engineer Handbook that gives many formulas and graphs that you can put into Excel etc. I have found one simple Excel program, I'm sure there are more on the net.
