摘要
液体推进剂晃动问题是航天飞行器的一个突出的动力学问题,通过耦合的欧拉-拉格朗日方法(CEL),对标准平底圆柱箱的充液晃动问题进行了计算,并和标准解进行了比较,验证了CEL方法的正确性。同时,采用CEL方法分析了囊式复杂贮箱的晃动问题,取得较好的效果,具有一定应用和推广价值。
The issue of liquid propellant sloshing is typical dynamics problem in the field of spacecraft. In this paper, with the Coupled Eulerian-Lagrangian（CEL）, a sloshing frequency of prefilled standard flat-bottomed column box is calculated. By being compared with the theoretical answer, the correctness of this method is validated. Meanwhile, by using CEL, a complex structure with prefilled rubber theca＇s sloshing frequency analysis is resolved. These simulation researches of sloshing of complex structure have good application and extension in the future.
