摘要
多星分离是一箭多星成功发射之关键技术,为保障卫星在轨顺利分离,需要在地面开展相关的分离试验及其仿真验证。本文针对带橡胶夹层的卫星自旋分离过程,进行了卫星分离地面试验方案设计和数值仿真。首先,给出了卫星分离地面试验设计方案;其次,采用自然坐标法分别对不带工装和带有工装的在轨卫星分离过程进行动力学建模及动态仿真分析;最后,研究了卫星⁃工装整体动力学建模及分离过程中带工装结构和不带工装结构对卫星分离的影响。
To ensure the successful separation of in-orbit satellites,it is necessary to perform ground experiments and dynamic simulations for the separation process in advance.In this paper,the separation process of spinning satellites with rubber sandwich is studied,and ground separation experiments are designed and simulated.First,the natural coordinate method is used to establish the dynamic model for the satellites.Then,the separation processes with and without tooling structures are simulated and analyzed.Finally,the dynamic modeling of the overall satellite-tooling structures is studied,and the effects of the tooling structure on the separation process are investigated.
