The invention relates to a device and method for regulating and controlling the curing residual stress of a propellant. The device comprises a base; a die cylinder is arranged above the base; a plurality of groups of stress reduction devices are assembled on the outer cylinder wall of the die cylinder in the axial direction of the die cylinder, and each group of stress reduction devices comprises a plurality of stress reduction devices which are uniformly distributed in the circumferential direction of the outer cylinder wall of the die cylinder; each stress reduction device comprises a high-energy acoustic beam transducer and a wedge block connected with the transmitting end of the high-energy acoustic beam transducer, and one end, opposite to the high-energy acoustic beam transducer, of the wedge block is tightly attached to the outer cylinder wall of the die cylinder; a supporting mechanism is arranged below the base, and a cavity is formed in the supporting mechanism; the high-energy acoustic beam transdu
