  "abstract": "During the loading process of a hydraulic column, the magnitude and distribution of stress in the cylinder barrel are critical to the safety of the hydraulic column. Aiming at the problem of stress distribution in the cylinder barrel of a hydraulic column under liquid pressure, a mathematical model of cylinder barrel stress is established based on the thick-walled cylinder theory and the fundamental theory of rotating shells. It is concluded that the main factors affecting the stress distribution of the hydraulic column cylinder barrel are the inner diameter of the cylinder barrel, the wall thickness of the cylinder barrel, and the height of the rodless chamber of the column. Numerical simulation, response surface methodology, and experimental research are adopted. The results show that the stress of the hydraulic column cylinder barrel exhibits an “M-shaped” distribution, with the stress peak located at the bottom of the cylinder barrel and near the piston. Among the selected structural parameters, the difference between the stress peak of the cylinder barrel and the stress valley at the cavity is most significantly affected by the height of the rodless chamber, followed by the inner diameter of the cylinder barrel, while the influence of the cylinder barrel wall thickness is the smallest. Through the response surface prediction model, it is found that when the inner diameter of the cylinder barrel is 230 mm, the wall thickness is 20 mm, and the height of the rodless chamber is 795 mm, the “M-shaped” characteristic of the stress distribution in the cylinder barrel becomes more obvious, which provides useful guidance for the design and safety assessment of hydraulic columns.",
