摘要
对多星与上面级非对称分离技术进行了研究。针对上面级多星非对称分离存在较大偏心的特点,通过优化调整,使用不同大小弹簧力的匹配抵消上面级转动的影响,减小了因卫星相对上面级偏心布置导致的分离力对卫星和上面级姿态的干扰。根据总体偏差量的概率模型,用蒙特卡洛仿真法统计出卫星姿态角和角速度的概率分布规律。
The dissymmetry separation technology between multi-satellite and upstage was studied in this paper. According to the characteristic of the large eccentricity exited in dissymmetry separation between muhi-satellite and upstage, the different appropriate spring forces were adopted to the effect of the upstage rotation by optimizing the parameters, which could decrease the attitude disturbance of the upstage caused by the separation of the satellites which were deployed eccentricity relative the upstage. Based on the probability model of general deviation, the probability law of the attitude angle and the angular velocity of the satellites was statisitied by using the Monte-Carlo simulation method.
