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.
