针对柔性太阳帆大变形引起姿态干扰力矩过大的问题,采用有限元方法对一种执行太阳极轨探测的150 m×150 m柔性太阳帆进行仿真分析,采用修正的压力加载方法降低了太阳帆在光压加载下的变形分析误差,获得了帆结构在大变形下由光压引起的干扰力矩。为降低干扰力矩量值、保证姿态稳定,提出了一种通过调整构型来降低变形量的方法,并通过仿真分析验证了该方法的有效性。
Aiming at the problem that the attitude disturbance torque caused by large deformation of flexible solar sail is too large, a finite element method is used to simulate a 150 m × 150 m flexible solar sail that performs detection of solar pole rails. The modified pressure loading method reduces the solar sail The error of deformation analysis under light pressure was used to obtain the disturbing torque caused by light pressure under the large deformation of sail structure. In order to reduce the magnitude of disturbance torque and ensure the stability of attitude, a method of reducing the deformation by adjusting the configuration is proposed. The effectiveness of the method is verified by simulation analysis.
