Launch vehicles' virtual test bed technology on separation applications

摘要

The characteristics of virtual test are low cost, short circle, high efficiency, and comprehensive application area, strong reusability and so on. As a kind of new technology, virtual test technology is gradually applied in each phase of complicated product design, to carry out system-level and multi-disciplinary work like analysis, valuation and optimization. In this paper, the background of virtual test is firstly presented, and the key technologies of virtual test bed are introduced. By using the bed, the study is given on stage separation and satellite-rocket separation and applications. Finally, conclusions and proposal are provided.
