摘要
本文研究低重力环境下贮箱内液体重定位运动的动力效应及其影响,概述了模拟低重力环境下液体重定位运动的落塔试验方法,利用小模型落塔试验测定了球型贮箱内液体重定位运动的作用力和作用力矩,分析了液体重定位运动的试验相似准则,讨论了液体重定位运动产生的动力效应对航天器的影响以及减小干扰的措施。
In this paper an investigation of the dynamic characteristics of liquid reorientation in a tank under low-gravity environment and the influence on spacecraft are described. The drop tower experimental method for simulated liquid reorientation in a tank under low-gravity environment is summarized. The forces and moments of liquid reorientation in a spherical tank are measured using a small model by drop tower test. The similitude criterions of liquid reorientation test are analysed. The influence of the dynamic behavior of liquid reorientation on spacecraft and the methods to reduce the disturbance are discussed.
