The assembly of the cylinder layers named "shrink fit” is done within certain shrinkage allowances. Thus, the compressive stresses created by the outer cylinder on the inner cylinder. Compressive stresses reduce the level of radial tensile stresses. In this study, the differences in stress levels of compound cylinders with different material pairs operating under ultrahigh pressure were investigated. In addition, the lightest cylinder that can be obtained by determining the optimum dimensions in compound cylinders with the same stress value has been investigated. And the weight savings that can be achieved in case this stress value is carried with a single layer cylinder has been determined. The maximum equivalent stresses in the cylinders were determined by the Finite Element Method (FEM). In this context, material pairs of Aluminium-Steel, Steel-Steel and GGG40 (Cast Iron)-Steel were used. According to the results of the analysis, 716 MPa equivalent stress was calculated under 350 MPa pressure in a single layer cylinder. This equivalent stress was reduced to 579 MPa by using the same amount of material with the Steel-Steel shrink-fit process. The optimum cylinder diameter dimensions with the same stress were determined. The total amount of steel used was 6.65 kg in a single-layer cylinder, this value decreased to 3.46 kg in the compound cylinder with optimum diameters. So, up to 52% of the amount of material was saved with the shrink-fit process.eninfo:eu-repo/semantics/openAccessContainerShrink-FitHydraulic CylinderMaterial Weight SavingConference Object
