Abstract

The invention provides a design method for assembling a meteorological satellite from top to bottom. The method includes the first step of carrying out functional description, conceptual design and structural decomposition on the meteorological satellite, determining the reference constraint and assembly relationship between structures of the meteorological satellite, scheming out required design parameters through the hierarchical design and the design that the top layer defines the overall situation, and outputting a layout design model, the second step of constructing a multi-framework model in hierarchical module units from top to bottom according to the layout design model, mapping the layout into the multi-framework model to achieve layout parameter-driven framework characteristics and outputting the multi-framework model, and the third step of carrying out detailed design on the solid characteristics of the module unit at the bottommost layer according to the multi-framework model, establishing specific engineering constraint and the like, carrying out engineering analysis on a detailed design model and outputting the detailed design model. Through the method, the limitation that the transfer path of the design parameters is single is overcome, the authority control of the design parameters is guaranteed, the high coupling performance between an upper-layer module and a lower-layer module is reduced, and reusing of the general module units is facilitated.

Description

technical field [0001] The invention relates to the technical field of meteorological satellite model product design, in particular to a top-down assembly design method of a meteorological satellite. Background technique [0002] During the research and development of meteorological satellite products, the design intentions are extensive, the reference relationship is complex, the design changes are frequent, and the authority control of design parameters between module units is strictly controlled. Meteorological satellite assembly design is an important link in the satellite development process. At present, the top-down design method is adopted. Transfer design method. In the top-down assembly design process of meteorological satellites, the establishment of skeleton models at all levels is the basis of the entire satellite design. By using the skeleton model to capture the design intent and build the product structure, the necessary design intent and reference relationsh...
