摘要
对小卫星单星偏心分离动力学进行了研究。建立了基于多体动力学理论的偏心在轨分离模型,用ADAMS平台对小卫星分离过程动力学进行仿真,结果显示两者误差小于0.15%,验证了仿真模型的正确性。用Monte-Carlo法对分离动力学性能进行了优化,分析了不同因素对分离角速度和分离速度的敏感度,给出了三种优化方案。
The separation dynamic of eccentric sub satellite was studied in this paper. The eccentric separation model based on multi-body dynamic theory was established. The dynamic during the separation was simulated by ADAMS software. The result showed that the error between the model and simulation was smaller than 0. 15%, which proved that model was correct. The separation dynamic was optimized by the Monte Carlo method. The sensitivity of various parameters on separation angular velocity and separation velocity was analyzed, The three optimization schemes were given out.
