摘　　要：基于大型运载火箭贮箱建立了不同挡板形式的贮箱缩比模型的试验研究方法,采用1∶8的缩比贮箱模型作为主要的研究对象,针对不同的挡板结构形式,如两块半圆形挡板、三块半圆形挡板和环形挡板,研究其液体晃动阻尼曲线,分析对比各种挡板形式的阻尼效率。针对3块半圆形挡板,研究其半径和层数对阻尼比的影响。A experimental researching method based on large launch vehicle tank has been developed to study the shrinking propellant tank model with different sloshing suppression baffle.The research object is a 1:8 shrinking propellant tank model.The liquid shaking cure of damping has been simulated with different sloshing suppression baffle such as double half-round baffle,tripe half-round baffle and ring-form baffle.According to researching of the tripe half-round baffle,the effect of damping by radius and quantity has been simulated,too.
