Nonlinear Dynamic Behaviors of Liquid and Space Structure in a Low Gravity Condition

研究了含液罐空间结构模型的非线性耦合动力特性。将其细分为两个主题，这个问题已经得到了解决。试验模型由直径为60mm的中央胶囊和长度为500mm的柔性梁作为太阳能板组成。试验模型在磁力作用下悬浮，在电磁力作用下激发。通过测量梁和主槽的频响曲线，明确了液体运动即晃动的影响。本文对水滴在振动平面上的非线性动力学行为进行了实验研究。在三种试验液滴设置的基础上，得到的试验液滴接触角不同。阐明了液体接触角、液体体积对液滴响应非线性的影响。

Nonlinear coupled dynamic behavior of a space structure model with liquid contained tank has been investigated. Subdividing it into two subjects the problem has been treated.I. Nonlinear dynamic behavior of space structure model with liquid contained tankTest model was composed of central capsule with 60 mm in diameter and 500 mm length flexible beams as solar panels. The test model was levitated by magnetic forces and was excited by electromagnetic force. The influence of liquid moving, i.e. sloshing was clarified by measuring the frequency response curves of a beam and main tank.II. Nonlinear dynamic behavior of a water drop on a vibrating planeNonlinear dynamic behavior of a water drop on a vibrating plane has been experimentally investigated.Three kinds of base on which test drop set has been used to obtain a test drop will different contact angle. The influences of liquid contact angle, liquid volume on the nonlinearity of a drop response has been clarified.
