Design and Optimization of a Solar Array Load Simulation System's Structure

太阳翼作为航天器能量来源的关键部件,它的特性直接影响太阳翼驱动机构(SADM)的输出特性。因此,研究设计一套模拟太阳翼特性的系统具有重要意义。基于振动动力学提出了一种模拟太阳翼的惯量与频率特性的机构,以机构的简化模型建立拉格朗日方程,分析惯量与频率之间的关系。根据技术参数要求,建立约束,完成结构参数的确定。利用matlab软件的fmincon函数,以占地面积为目标进行优化设计,有效地减少了占地面积。

As the key component of the spacecraft＇s energy source, the solar array＇s properties affect the output charac- teristics of the Solar Array Drive Mechanism（SADM） directly, therefore, to design a system simulating the characteristics of the solar array had an important significance. Based on vibration dynamics, put forward a mechanism simulating the inertia and frequency characteristics of the solar array. According to the simplified model of the mechanism, establishing the Lagrange equation analyzing the relationship between the inertia and frequency. According to the requirements of technical parameters, establishing the constraints, finished the determination of structure parameters. Using MATLAB＇s fmincon function, optimized the mechanism aimed at the covering area, reduced the area effectively.
