火箭着陆装置油气缓冲器的缓冲性能分析
Analysis of oil & gas buffer performance on rocket landing devices
摘要
Abstract
To reduce space exploration costs and boost launches,reusable rockets are developed.For these rockets,landing gear buffering is of paramount importance.Based on hydro-pneumatic spring principles,a shock absorber design is introduced.Based on Boyle's Law and orifice theory,this paper proposes a math model and a performance index-comprehensive error.Simulations are conducted to analyze dynamics,flow field,and stress and verify its feasibility.Prototypes undergo bench and drop tests.Results show the shock absorber's comprehensive error is 2.63％,and max support force error is 2.5％,demonstrating the model's superiority and providing some insights into the design of reusable rocket landing devices.关键词
