Abstract
A method of manufacturing a pressure accumulator, using an AE signal for the pressure accumulator, includes: a first estimation step of estimating with an AE sensor provided at the pressure accumulator, a range of stress levels at each of which a damage AE signal that is generated from the pressure accumulator because of damage of material of the pressure accumulator is in a predetermined state; and a first design step of designing the pressure accumulator such that a minimum thickness of the pressure accumulator is determined based on the stress level range estimated in the first estimation step.
