According to the method, the shell of the cabin plate three-dimensional model is rapidly extracted, the obstacle of the digital technology between design and simulation is broken through, the three-dimensional model information is rapidly and effectively transmitted and fed back to the simulation modeling process in a lossless mode, the satellite simulation efficiency is improved, and the cost is reduced.
Description
technical field [0001] The invention relates to the technical field of aerospace vehicle structures, in particular to a method and system for quickly extracting a shell simulation model based on a satellite deck structure. Background technique [0002] At present, the development of satellites is faced with the situation of simultaneous development of multiple models, high-density launches, high quality and reliability requirements, and short development cycle requirements. High-quality, high-efficiency, and high-benefit satellite structure design is required, which requires refined and rapid structural design simulation, and the ability to quickly adapt to structural design changes and continuously iterate. [0003] The existing satellite simulation modeling methods are basically separated from the 3D design, requiring designers to handle the transfer of design information between design and simulation. In order to solve the above problems, the object of the present invent...
