| Abstract: | A mathematical model of the analysis and calculation of the prestress of a hydraulic multi-layer bound cylinder was founded using the interference theory of shrinking internal cylinder and extending external layer,a new analysis and calculation method of the hydraulic multi-layer bound cylinder was proposed for the optimization and stress predication of the hydraulic bound processes.Some calculations were performed using practical examples,and the calculation results were compared with the hydraulic testing results of the cylinders,the total stresses and deformations of the cylinders conformed to the HG3129-1998 standard and ASME codes（ULW-77,ULW-78）. |
