针对空间绳网捕获应用,进行了多收口质量块收口过程的动力学分析。以一种自适应双卷筒卷取机构为研究对象,考虑包含有三个质量块的收口系统,通过建立收口质量块质点运动微分方程、收口绳长约束方程并利用非正交变换方法,给出了各收口质量块质心运动与缆绳卷取运动耦合的动力学模型,仿真分析了质量块平动发射和系统自旋发射等典型收口过程的运动特点,给出了一些收口过程的驱动控制策略,同时也说明此类自适应收口质量块具有较强的自适应性和容错性,适用于空间绳网捕获系统。另外,以上分析也适用于采用缆绳控制的绳系卫星编队系统。

英文摘要：

Dynamics of the take-up process is analyzed in the application of take-up system into space tethered-net capture. Dynamic model of the coupling between the motion of the mass center of mass blocks and the coiling motion of tether for a take-up system with three mass blocks is developed with the help of non-orthogonal transformation, considering the differential equations of the mass block and the constraint of tether length. Motion characteristics of several typical take- up processes, such as translational emission of the mass blocks and spin emission of the system, are simulated and some drive strategies for the take-up process are thus proposed and validated. It is shown that this kind of adaptive take-up mass blocks is strongly self-adaptive and fault tolerant and thus appropriate for space tethered-net capture system. Besides, above analysis is also applicable to the tether-controlled space tethered satellite formation system.
