Abstract
The invention discloses a paraboloid and formation method of a satellite-borne paraboloid reflecting antenna based on an elastic plate with the gradually varied thickness, and belongs to the technical field of satellite-borne antennas. The problems that an existing paraboloid reflecting antenna is complex in formation method and low in accuracy are solved. The satellite-borne paraboloid reflecting antenna based on the elastic plate with the gradually varied thickness comprises two mandrels, a reflection face and a pulling device, wherein the reflection face thins gradually from left to right and is arranged between the two mandrels; the pulling device comprises two cords and two motors; the two motors are arranged at the two ends inside one mandrel and are connected with one ends of the two cords respectively, and the other ends of the two cords are connected with the two ends of the other mandrel respectively. According to the formation method of the satellite-borne paraboloid reflecting antenna based on the elastic plate with the gradually varied thickness, the cords are shortened through the motors, the two mandrels get close and compress the reflection face, and the reflection face is made to deform and arch. The paraboloid of the satellite-borne paraboloid reflecting antenna based on the elastic plate with the gradually varied thickness is used as the reflection face of the satellite-borne antenna.
Description
Technical field
The invention belongs to satellite antenna technical field, be specifically related to a kind of parabola and manufacturing process thereof of the spaceborne parabolic reflector antenna based on progressive thickness elastic plate.
Background technology
Inflatable structure and thin film technique are widely used in antenna space field in recent years.Flexible parabolic reflector antenna can curlingly fold before launching with it, takes in than height, and the feature that throw-weight is low is more and more subject to the attention of various countries.Yet how to make flexible parabolic reflector antenna in curling rear expansion moulding and to reach design accuracy be a difficult point, someone proposes the molding mode that rigid hinge adds guide plate, but restive and realize, existing manufacturing process is all very complicated, and precision is low.
Summary of the invention
The object of the invention is in order to solve existing flexible parabolic reflector antenna manufacturing process complicatedly, and the low problem of precision, provides a kind of parabola and manufacturing process thereof of the spaceborne parabolic reflector antenna based on progressive thickness elastic plate, and its technical scheme is as follows:
A spaceborne parabolic reflector antenna for progressive thickness elastic plate, it comprises two axles, reflectings surface and reels device, and described two axles adopt carbon fiber pipe, and two axles be arranged in parallel; Described reflecting surface adopts Elastic Carbon fiber plate, reflecting surface is gradually thin from left to right, and its thickness adopts the mode of linear function to change, and reflecting surface is arranged between two axles, the two ends, left and right of reflecting surface are connected in two axles by dentation carbon cloth respectively, and dentation carbon cloth and reflecting surface pass through rivet; The described device that reels comprises two strings of a musical instrument and two motors, and described two motors are arranged on the two ends, inside of an axle, and two motors are connected with one end of two strings of a musical instrument respectively, and the other end of two strings of a musical instrument is connected with the two ends of another axle.
A manufacturing process for the spaceborne parabolic reflector antenna of progressive thickness elastic plate, utilizes motor to shorten the string of a musical instrument, makes the close also compressive reflexes face of two axles, reflecting surface is deformed and arch upward.
Beneficial effect of the present invention is: the invention solves molding mode complexity, the low problem of precision that current spaceborne parabolic reflector surface antenna exists.A kind of curling reflecting surface and axle connected mode of being applicable to proposed, designed the carbon fiber reflecting surface that a kind of thickness changes in linear function mode, it is parabola shaped that the thick carbon fiber board of this gradual change just can make its shape approximation through simple compression, thereby reaches designing requirement.

embodiment:
A spaceborne parabolic reflector antenna for progressive thickness elastic plate, it comprises two axles 1, reflecting surface 2 and reels device 3, and described two axles 1 adopt carbon fiber pipe, and two axles 1 be arranged in parallel; Described reflecting surface 2 adopts Elastic Carbon fiber plate, reflecting surface 2 is gradually thin from left to right, its thickness adopts the mode of linear function to change, reflecting surface 2 is arranged between two axles 1, the two ends, left and right of reflecting surface 2 are connected in two axles 1 by dentation carbon cloth 4 respectively, and dentation carbon cloth 4 passes through rivet with reflecting surface 2; The described device 3 that reels comprises two string of a musical instrument 3-1 and two motor 3-2, described two motor 3-2 are arranged on the two ends, inside of an axle 1, two motor 3-2 are connected with one end of two string of a musical instrument 3-1 respectively, and the other end of two string of a musical instrument 3-1 is connected with the two ends of another axle 1.
A manufacturing process for the spaceborne parabolic reflector antenna of progressive thickness elastic plate, utilizes motor 3-2 to shorten string of a musical instrument 3-1, makes the close also compressive reflexes face 2 of two axles 1, reflecting surface 2 is deformed and arch upward.
Inventive principle: the two ends, left and right of reflecting surface 2 are connected in two axles 1 by dentation carbon cloth 4 respectively, easily curling, in uneven thickness due to reflecting surface 2, so the reflecting surface arching upward is symmetrical arch, because reflecting surface is the Varying Thickness Plates that adopts linear function, so its rigidity is not symmetrical, it only can arch upward to a direction, and its shape is approximate parabola as calculated.
