Hydraulic cylinder (Shell) stresses

Click For Summary
SUMMARY

The discussion centers on the analysis of stresses in the shell of a double-acting hydraulic cylinder, specifically regarding the importance of longitudinal stress in addition to radial and circumferential (hoop) stress. It is established that while longitudinal stress is negligible in open-end cylinders like gun barrels, its relevance in hydraulic press cylinders warrants consideration. The conversation highlights the necessity of understanding stress distribution in hydraulic machinery, particularly in relation to safety mechanisms such as relief valves set below bursting pressure.

PREREQUISITES
  • Understanding of hydraulic cylinder mechanics
  • Knowledge of stress analysis principles
  • Familiarity with radial and circumferential stress concepts
  • Awareness of hydraulic safety systems, including relief valves
NEXT STEPS
  • Research the principles of stress analysis in hydraulic systems
  • Study the design and safety features of hydraulic cylinders
  • Learn about the effects of pressure on different stress types in cylindrical structures
  • Explore the role of relief valves in hydraulic machinery safety
USEFUL FOR

Mechanical engineers, hydraulic system designers, and safety engineers involved in the design and analysis of hydraulic machinery and components.

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
