| 摘 要： | 液体推进剂的晃动特性对大型液体运载火箭以及战略弹道导弹的飞行动力稳定性有着很大的影响。为了使战略弹道导弹和航天运载器具有良好的飞行稳定性，就必须提高其内部液体推进剂的晃动阻尼，抑制液体的晃动，从而达到动力稳定的设计要求。常用的增加液体晃动阻尼的措施是在推进剂储箱内安装防晃挡板。横向环形挡板是一种常用的防晃挡板。本文对它的防晃特性进行了初步的分析，得到了一些有益的结论。

| Abstract: | The dynamic behavior of the liquid sloshing has great effect on the dynamic stability of the liquid filled space vehicle and the strategical ballistic missle. The liquid slosh has to be suppressed to meet design requirements of the flying dynamic stability. For this purporse, the slosh damping of the liquid in the container has to be increased. Measures usually taken in the astronautical engineering are to install baffles in the propellant fuel container.The ring baffle is often used in the liquid container of the rocket for liquid slosh suppression. A rough analysis of the suppression effect of the ring baffle on the liquid slosh in a cylinderical tank is carried out , and some valuable results are presented. |
