一种提高太阳能帆板受晒效率方法

为提高航天器空间太阳能利用率,提出了一种可实现帆板对日定向功能的改进太阳能帆板双自由度驱动机构。根据航天器的轨道理论推导出在对日定向要求下太阳能帆板的运动规律和机构的运动轨迹,并给出了双自由度驱动机构的轨迹规划和驱动轴实时转角。仿真结果表明:用该法能实现帆板的对日定向,提高其受晒效率,对未来航天器太阳能帆板驱动机构设计与控制有一定的参考价值。

A Method to Improve Sunshine Efficiency of Solar Array

To improve the using efficiency of the solar energy on spacecraft,a new mechanism to drive the solar array with the function of directing to the sun was put forward in this paper.The movement rule of the solar array and the track of the mechanism under the need of directing to the sun based on the theory of spacecraft orbit were derived,and the track planning of the driving mechanism with dual freedom and real time rotation angle of the moment axis were also given out.The simulation results showed that the directing to the sun of the solar array would be implemented with improved sunshine efficiency using the new method,which was valuable to the design and control of the solar array driving mechanism of the future spacecraft.
