摘要
防晃板是运载器贮箱内一种有效的防晃措施。本文实验研究了刚性和柔性防晃板对液体晃动的抑制作用,分析了液体晃动频率和晃动阻尼,研究了影响防晃板防晃性能的各种因素,比较了刚性和柔性防晃板的防晃特性,同时还对三种不同材料、不同规格的柔性防晃板的防晃性能进行了研究,并得到一些有益的结论。
The baffle installed in the propellent tank is an effective measure of anti-sloshing.In this paper, slosh-suppression effectiveness of flexible and rigid baffles is studied experimentally. We analyze the slosh frequency and slosh damping, research into the various factor affecting the behavior of baffle, and compare the effect of rigid and flexible baffles. And we study the baffling behavior of three kind of flexible baffles whose materials are different, Some valuable results ae obtained.
