| 摘 要： | 偏心安装的子卫星在轨分离是一类特殊的卫星在轨分离问题。为了给分离地面试验和分离系统设计提供依据,在惯性参考系中分析了筒式偏心在轨分离问题的运动特性。以刚体运动学原理和动力学动量定理、角动量定理及能量定理为依据,建立了分离过程的动力学模型。运用数值求解方法,给出了不同初始条件下的模型求解算例,并对求解结果进行了比较和分析。分析结果表明,分离弹簧物性参数是影响分离速度的主要因素;卫星相对安装位置是影响分离角速度的主要因素。

| Abstract: | The constrained and centroid biased on-orbit satellite separation,which a sub-satellite fits in with a centroid offset,is a special kind of on-orbit satellite separation problems.In order to provide references for the ground separation tests and the separation system design,characteristics of the constrained and centroid biased on-orbit satellite separation were analyzed in inertial reference frame.By using kinematics principles of a rigid body,as well as momentum theorem,angular momentum theorem and kineti... |
