卫星太阳翼阻尼器参数选定方法

Selecting method of damper parameters for solar array of satellite

摘要:

为了研究阻尼器参数(位置、数量及阻尼大小)在锁定过程中对锁定冲击力矩及帆板展开到位过程中对卫星姿态角的影响,在卫星太阳翼系统建模的基础上,利用MSC.ADAMS动力学软件对太阳帆板展开过程进行了仿真分析,对展开过程中帆板之间的冲击力矩以及卫星姿态角变化进行了分析.结果表明:在连接架与帆板间施加单阻尼器可以有效地减小帆板间的锁定冲击力矩及卫星姿态角变化.对各种工况进行了分析、总结,提出了阻尼参数的选择方法.

Abstract:

To investigate the influence of different damper parameters(position,number and size) on the change of attitude angle of satellite during the locking process,based on the model of wing system of satellite,the attitude dynamics of the deployment of solar wing process is simulated by the MSC.ADAMS software.The change of attitude angle of satellite and the wallop between the wings during deployment process are investigated,and the influence of different damper parameters is analyzed.The result demonstrates that the damper imposed between the yoke and panel can effectively reduce the wallop and the change of attitude angle of satellite during the locking process.Finally,a selecting method of damper parameters is put forwards.
