摘　　要：简要介绍异面构型太阳能电池阵的构型及其展开过程.由于动力学耦合作用的存在,异面构型太阳能电池阵的展开运动会对飞行器的姿态产生影响,根据对系统角动量守恒方程的分析,采用余弦函数参数化关节角的运动轨迹,以太阳能电池阵运动前后航天器的姿态变化量为优化目标,通过遗传算法进行参数的寻优,最终得到一条对航天器姿态影响相对较小的太阳能电池阵的展开运动轨迹.给出一种异面构型太阳能电池阵机构,通过对其展开过程进行仿真分析,证明了所提方法的有效性.The configuration and deployment of non-coplanar solar arrays are introduced briefly.Because of dynamic coupling effects,the deployment process of the non-coplanar solar arrays affects the attitude of the spacecraft.The angular momentum equation is analyzed and the joint path is parameterized by a cosine function.Then,the objective function is defined according to the variation of the spacecraft attitude.At last,genetic algorithm is adopted to search the optimal parameters which are used to obtain a path that when the non-coplanar configuration solar arrays deploy according to this path,its affect to the spacecraft will reduce to a relatively very small range.At last,one kind of non-coplanar configuration solar arrays is given,and the effectiveness of above method is verified by simulation results.
