太阳电池阵地面展开仿真技术研究与试验验证

基于动压头简化公式、3D-FLUENT 全流场仿真以及附加质量方法, 针对实践七号(SJ-7) 太阳电池阵地面展开系统进行了研究, 首次实现了多体动力学与空气动力学实时耦合计算在太阳电池阵研究上的应用. 三种仿真计算方法所得结果相互得到了验证, 在计算精度方面大大优于以往做法, 同时与地面试验实测结果得到了很好的统一. 该方法目前已成功应用于其他在研型号任务. 

Ground Dynamics Simulation and Experiment of Solar Array

The research of Shijian-7 (SJ-7) solar array deployment on the ground was carried out using three methods,such as dynamic pressure simple formula,3D-FLUENT simulation and generalized additive inertia method.For the first time the real-time coupling calculation was realized between multibody system dynamics and aerodynamics,and which is successfully applied on the research of the solar array.The results of the three different methods validate each other and get better precision than previous method.At the sa...
