According to the whole design process of demand parameter input, structural design and strength analysis of products, rapid automatic optimization, rapid automatic modeling, automatic finite element model establishment, an automatic rapid finite element solution, automatic drawing of typical parts and process data management of the design process are realized by using a parameterized design idea, a modular system constructing technology, a database technology, a digitalized modeling technology, a finite element analysis technology, full-digitalization design and an analysis module customizing technology and fusing an automatic optimizing design method, a knowledge-driven design method and a top-down design method; the whole-process design acceleration is realized, the design efficiency is increased and the development cycle of products is shortened.

Description

technical field [0001] The invention relates to the technical field of modeling, in particular to a modular-based rapid design analysis and optimization system for large structures. [0002] Background technique [0003] The design of large-scale structures, especially those related to spacecraft, often has a complex structure and many parts, but the structural configuration of the new cabin generally changes little, mainly to meet the needs of model tasks, and the structural parameters and bearing loads are the same. Design of configuration structures. With the increase of aerospace missions, the requirements for the R&D cycle increase, and the R&D units are facing increasing pressure on product quality, mission nodes and costs. Traditional design methods have duplication of design work, repeated definition of design parameters, low design efficiency, and parameter transfer. Without a unified format, it is generally transmitted through drawings and documents, which is lik...
