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.
