Hydraulic cilinder
Hydraulic cilinder
(OP)
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 hydraulic cylinder (as in presses hydraulic cylinder) 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

RE: Hydraulic cilinder
For a double-acting hydraulic cylinder, you'd get longitudinal tension on the wall when retracting?
RE: Hydraulic cilinder
So longitudinal stress should be considered(I mean they're not zero) for double-acting cylinder?
RE: Hydraulic cilinder
This applies whether you're pulling a load in, or braking an overhauling load as it pulls the rod out.

I couldn't find anywhere exact definition what is closed end and what open end cylinder.
P.S. It's maybe obvious for you but I'm not that experienced and English is not my first language.
RE: Hydraulic cilinder
By contrast, single acting cylinders are "open" to the atmosphere at one end. There's nowhere to pump oil in; if you did, it would just come out again and, importantly, you can't pressurise that end of the cylinder.
