摘　　要：基于柔性多体动力学方法,开展了大口径环形展开反射器的展开过程动力学仿真,给出了展开过程电机驱动力曲线及杆件受力情况;对展开过程驱动力做功、展开过程能量消耗情况及展开不同步现象进行了分析。在此基础上,提出对展开过程施加约束的方法,以实现对展开过程驱动力做功及能量使用分布进行优化,并提出了降低展开驱动力和杆件受力的可行方法。Dynamics of deployment of the large hoop-truss deployable reflector is studied in this paper. The driving force of motors and the bending moments of the members of the hoop-truss are obtained. The work of driving cable and the energy used are analyzed during deployment. Particularly,the nonsynchronous deployment is focus in the paper. On the basis of the above results,the appropriate constraints of deployment are studied to accomplish deployment optimization,with the purpose of reducing the maximum value of motors driving force and the bending moments of the members in the hoop-truss.
