摘要
进行液体推进剂贮箱的防晃设计是解决充液航天飞行器由于液体晃动而产生的动力不稳定问题的主要技术途径。文中讨论了贮箱防晃设计的两类主要方法──液体晃动的结构控制和阻尼控制的防晃机理、防晃特性描述方法、结构实现途径及适用性，并提出了一些在防晃设计中应进一步研究的问题。
The design of sloshing suppression for liquid propellant tanks is the major technical way to solve the problems of dynamic instability of spacecraft partially filled with liquid which is produced by liquid sloshing. In this paper, the mechanism of sloshing suppression and description of properties of sloshing suppression and ways of realization in tank′s structure design and applicability of two kinds of major methods for design of sloshing suppression in tanks──the structural control and damping control of liquid sloshing──are discussed. The major structures of sloshing suppression which have being used to spacecrafts and their characteristics are introduced. Some problems of the design of sloshing suppression which need investigating further are proposed.
