The invention discloses a tubular hinge with asymmetric thin shells unfolding in an elastic damping manner, and a manufacturing method of the tubular hinge, and belongs to the field of hinges for unfolding solar panel substrates of small satellites. A conventional hinge for unfolding solar panel substrates of small satellites is high in cost, and the stress of the conventional hinge cannot be controlled or neutralized, so that the hinge shifts and is not correctly controlled during unfolding. According to the tubular hinge with asymmetric thin shells unfolding in an elastic damping manner, two oblong holes (3) are formed in a bending section (2) of a round rube (1) to form a main bending thin shell (4) and an accessory bending thin shell (5); damping springs (6) are arranged between the main bending thin shell (4) and the accessory bending thin shell (5); both ends of the round tube (1) are fixed to both ends of a W folded plate (8). The manufacturing method of the tubular hinge comprises the following steps: designing a penetration method of the oblong holes (3); arranging the damping springs (6) between the main bending thin shell (4) and the accessory bending thin shell (5); and determining the hinge unfolding angle of the round tube (1). The tubular hinge has the advantages of being stable during unfolding, low in cost, long in service life, and high in precision.
