Method for forming shaped convex surface type high-precision reflection panel with honeycomb sandwich structure

Abstract

The invention provides a method for forming a shaped convex surface type high-precision reflection panel with a honeycomb sandwich structure. The reflection panel particularly comprises three layers of aluminum plates, two layers of honeycomb cores and a plurality of embedded parts for connecting, wherein the three layers of the aluminum plates comprise a work plate, a middle connecting plate and a back plate. The formation method at least comprises the following steps of: three-dimensional modeling of three layers of plates of the shaped convex surface type high-precision honeycomb sandwich structure, space geometric flattening of the three layers of the plates, establishment of a process compensation surface, calculation of a nail height and positioning of the three layers of the plates on a high-precision nail bed; and a process of paving a sandwich structure layer by layer is a main process of manufacturing the shaped convex surface type reflection panel. According to the method provided by the invention, the manufacturing problem of the shaped convex surface type high-precision reflection panel and the manufacturing difficulty of the shaped convex surface type reflection panel with sharp points are solved, thereby realizing a manufacturing target of a shaped convex surface type antenna reflection panel which has the advantages of high precision, large rigidity and light weight.

Description

technical field [0001] The invention relates to a forming method of a high-precision honeycomb sandwich structure reflection panel with a shaped convex surface, and belongs to the field of mechanical engineering / sheet material forming. Background technique [0002] With the rapid development of satellite communications, radio measurement and control, deep space exploration, and large radio telescopes, not only the demand for antennas is more and more extensive, but also higher requirements are placed on the accuracy of the antenna reflector. As a secondary surface of a radio telescope, it is used to collect feedback signals from the entire main surface. Although the area of ​​the secondary surface is much smaller than that of the main surface, and the diameter of the secondary surface is only one tenth of the diameter of the main surface, the surface accuracy of the secondary surface is usually much higher than that of the main surface. The surface accuracy requirement of t...
