Pneumatic piston cylinder design

AI Thread Summary
The discussion focuses on designing and simulating a pneumatic piston cylinder, specifically calculating the force profile of the piston over time. It emphasizes that the force is dependent on fluid pressure, which varies as the piston moves. Participants suggest using a polytropic process to model gas pressure changes during the piston stroke. There is a request for assistance in developing differential equations with time as a variable. The conversation highlights the need for simulation software suitable for pneumatic systems.

Freinds,
I have to design and simmulate a pneumatic piston cylinder, and want to calculate force profile of piston with time. please help me in this regard, also please tell me any simmulation software simmulating pneumatic piston cylinder.

The force will be a function of the fluid pressure (air in this case). The pressure will change as the piston strokes (in or out). Use a polytropic process to model the gas pressure.

yes ofcourse force will be a function of the fluid pressure. but i have to developed differential equations with time as a dependent variable. please help me in this regard.
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
