Abstract
The invention discloses a bending-forming-based parabolic cylinder antenna reflector and a method for the reflector to achieve a parabolic cylinder, and belongs to the technical field of satellite-borne antennae. The problems that satellite-borne parabolic cylinder antennae are heavy, large in size after being curved, small in rigidity and low in face forming accuracy are solved. The bending-forming-based parabolic cylinder antenna reflector comprises a mandrel, a supporting plate, a film reflector, a film inflating tube, elastic buckles and a hauling cable. The method for the bending-forming-based parabolic cylinder antenna reflector to achieve the parabolic cylinder includes the steps that first, an air tank and other inflating devices are used for inflating the film inflating tube through an inflating opening, then, the hauling cable is rolled and shrunken through a motor and the like to combine the elastic buckles, the supporting plate and the film reflector bend along with combining of the elastic buckles so that the parabolic cylinder can be formed, and finally, the supporting plate and the film inflating tube are toughened through ultraviolet irradiation. The bending-forming-based parabolic cylinder antenna reflector is used as a satellite-borne antenna reflector.
