Abstract
Millimeter and sub-millimeter wave observations, however, which largely depend on the instrumentation techniques, provide vital experimental verifications for the theoretical studies of stars formation. To obtain the stronger and more precise radio spectrum signals, high precision reflector panels that are demanded in great amount especially for the largeaperture antenna and antenna-array. Many years, experts have put emphasis on the precise forming of reflector panels. This paper presents the high-precision panels with a sandwich-type construction of one skin-plate and one aluminum backup structural combined with structural adhesive, with high precision modules as the fundamental condition. The skin-plate fit the module well due to its flexible. The structural adhesive, with good flow-ability, automatically compensate the deviations between the skin-plate and the backup structural. In the end, individually shaped sandwichlike panels assemble up the high surface-accuracy reflectors. The internal stress analysis of skin-plate and structural adhesive are of utmost importance. Therefore, several kinds of skin-plate and structural adhesive in different material properties are listed and simulated with finite element method (ANSYS). Based on the simulation results, processing parameters to panel fabrication are determined more efficient and accurate.
