Hydraulic cylinder (Shell) stresses

AI Thread Summary
In analyzing the stresses in the shell of a double-acting hydraulic cylinder, both longitudinal and circumferential (hoop) stresses should be considered, alongside radial stress. While longitudinal stress is often deemed less critical in open-end cylinders, its relevance in hydraulic press cylinders warrants attention due to the potential for significant pressure differentials. The discussion draws an analogy between hydraulic pistons and bullets, highlighting the importance of understanding stress dynamics. Additionally, it is noted that hydraulic systems are equipped with relief valves to prevent pressure from exceeding safe limits. Proper analysis of all stress types is essential for ensuring the safety and functionality of hydraulic machinery.

Hello guys,
this is my first time here take an apology if I choose wrong section of forum.
I just want to know should in shell of double-acting hydraulic cylinder (as in hydraulic presses ) should longitudinal/axis stress be analyzed beside radial and Circumferential/hoop stress and take in consideration.
I searched everywhere and couldn't find answer. I know that longitudinal stress is not important for open end cylinder such as gun barrel, but what about hydraulic press cylinder??

Thanks in advance

Since this post has not been answered for 2days I'l take a gander.
Imagine the hydraulic piston to be the bullet in a gun. Any similarities?

Also if it were to be blocked all hydraulic machinery has relief valves set to much below bursting pressure

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...
