卫星二次分离方案仿真研究

首先借助Adams软件对多星二次分离方案建立简化的分离系统模型,研究卫星质量,子星分布特性,分离参数等因素对小卫星二次分离的影响,并选择合理参数值对多星二次分离过程仿真。然后,为验证模型,对二次分离进行了动力学计算,得到子星分离速度和角速度值。对比两者结果一致,验证了ADAMS模型计算的正确性。仿真研究对小卫星设计具有重要实际意义,为我国新一代小卫星的多级分离技术的研究提供依据和参考。

Abstract：

Firstly,the simplified model of satellite separation system was built for secondary separation schemes,and the elements of affecting micro-satellite secondary separation were analyzed,such as micro-satellite mass,distributing character and separation parameters,and then ADAMS simulation was applied to the multi-satellites secondary separation based on the optimized parameters. After that,in order to verify model,the dynamic calculating was carried out and velocity and angle velocity of secondary separation were obtained. Finally,it could be concluded that the Adams model was correct comparing dynamics results. The results are a good reference to satellite design and step separate technology of new generation satellite.
