Theoretical analysis has been conducted on the free hydroelastic coupled vibrations of a thin sector shell with attached liquid layers in a low-gravity condition. Experimental studies were also conducted on the vibration of liquid drop within the range of those carried out on the grand. The study is subdivided into two parts.I. Theoretical analysis on the free hydroelastic vibration of a thin sector shell with attached liquid layers inside and/or outside the shell wall.Flugge thin shell theory and velocity potential theory were used, and the influences of surface tension of the liquid, geometry of the shell, and material parameters of the system, on the coupled vibration characteristics of the system were clarified.II. Experimental study on dynamic behaviors of liquid drop on a vibrating base.Water drop was used was excited harmonically The conditions at which the water drop removes from the base, and at which the water separates in itself.

本文对低重力条件下带有液层的扇形薄壳的自由水弹性耦合振动进行了理论分析。在此基础上，对液滴的振动进行了实验研究。本研究分为两个部分。采用Flugge薄壳理论和速度势理论，对壳壁内外均附着液体层的扇形薄壳的自由水弹性振动进行了理论分析，阐明了液体表面张力、壳体几何形状和系统材料参数对系统耦合振动特性的影响。振动基座上液滴动力学行为的实验研究采用简谐激励水滴，研究水滴从基座上脱落和水自身分离的条件。
