| 摘 要： | 用等效力学模型法研究了多腔体充液晃动问题.在单腔体等效模型的基础上给出了多腔体充液体的等效模型,并分析了液体分散到多个腔体后对飞行器带来的影响.结果表明,从频带的改善到作用力的减少等方面,一般情况下多个腔体的力学特性更有利于飞行器的动力学与控制设计.

| Abstract: | Using the equivalent mechanical model,this paper investigated multi-tank liquid sloshing problem.The multi-tank equivalent mechanical model was presented based on the single tank equivalent model,and the mechanical effects of the multi-tank sloshing on spacecraft were analyzed.The results show that the frequency and mechanical characteristics of the multi-tank system are usually better than its single counterpart for dynamics and control design of a spacecraft. |
