【摘要】 液体晃动是一个在充液航天器总体设计中必须考虑的问题，随着航天事业的飞速发展，推进剂占火箭、卫星等航天器总重量的比重不断加大，推进剂的运动对在轨航天器的稳定、控制、定位、对接的影响都是关键的．因而，需要对液体晃动做更深入的研究．液体燃料系统是航天器复杂大系统的一个子系统，在进行整个系统分析时需要考虑到液体与结构之间的相互作用，这样就必须进行液固耦合力学的研究．本文对与航天工程相关的液体晃动问题和液固耦会动力学问题的研究方法进行了简要介绍，概要性综述了这些问题的研究进展．更多还原

【Abstract】 Liquid sloshing is a problem which must be considered during general design of liquid-filled spacecraft.With the rapid development of space engineering, liquid propellants form a larger and larger fraction of spacecraft,and the influence of liquld propellant in motion on stability, control, orientation, docking of spacecraft is considered critical .So, liquid sloshing should be further investigated. The liquid propellant is a complicatal subsystem of spacecraft and the interaction between liquid and structure must be considered during the analsis of the whole sys-tem and the liquid-solid coupled dynamics should be studied. The research method for studying liquid sloshing and liquid-solid coupled dynamics is summarized and the advancement of inveshgation into these problems relating to space engineering is reviewed.更多还原
