A rapid spacecraft quality characteristic analysis method includes the steps: firstly, forming a quality information summary table according to equipment interface data sheet records of a spacecraft; using an interface tool for importing the quality information summary table into a spacecraft equipment model; secondly, using the interface tool for exporting position information and quality information of the equipment model to form an equipment model position and quality information summary table, and computing the position information and the quality information in the equipment model position and quality information summary table by the aid of a quality characteristic computational formula to obtain quality characteristic results of the spacecraft; and thirdly, using Pro / E software for quality characteristic analysis of the spacecraft, comparing analysis results with the quality characteristic results obtained in the second step, and if comparison difference is within a preset range, completing rapid quality characteristic analysis of the aircraft. The computing method overcomes shortcomings of an existing method of a quality characteristic analysis system, and achieves real-time update of quality characteristic information, rapid acquisition and scientific inspection of computational results and the like.
Description
technical field [0001] The invention relates to a method for quickly analyzing quality characteristics of a spacecraft, which is used for assisting configuration layout design and general assembly design of the spacecraft. Background technique [0002] The mass characteristic is a characteristic of the spacecraft itself, mainly including mass, center of mass coordinates, moment of inertia, product of inertia, etc., and is an important input for spacecraft attitude and orbit control strategies. In order to reduce the limitation of ground measurement and control capabilities, domestic spacecraft usually adopt optimized attitude and orbit control strategies, and put forward counter requirements on the quality characteristics of the entire satellite, and clarify that the quality characteristics do not exceed a given range. In view of the importance of quality characteristics, quality characteristic analysis has long been an important work content in spacecraft configuration layo...
