| 摘 要： | 用偶极子配置法分析太阳帆板振动时所诱导的空气流场，导出其流动的动能表达式，并在此基础上得到了空气的附加质量矩阵，只要给定真空中太阳帆板自由振动的主模态和对应的主频率，就可以分析帆板与空气耦合系统的固有振动特性。

| Abstract: | Air flow induced by vibration of solar array is analyzed using doublet configuration method. The kinetic energy of the flow field is described in doublet intensities. Added mass of air flow can be derived from the expression of kinetic energy. Then the coupled vibration of solar array and air flow can be calculated with component modes synthesis method. One may consider the influence of air to the natural frequencies of the solar array. |
