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。
Aiming at the application of space rope netting, the dynamic analysis of multi-inlet mass block closing process was carried out. Taking an adaptive double-reel take-up mechanism as the research object, considering the system of three-block receiving system, the constitutive equations of the mass of the receiving block are established, and the constraint equations of the length of the rope are closed and the non-orthogonal transformation method is used The kinetic model of the coupled mass centroid movement and the cable take-up motion was analyzed. The motion characteristics of the typical shut-in process such as mass translation and system spin-emission were simulated and analyzed. Some driving control strategies were given, At the same time, it also shows that the self-adaptive receiver block has strong self-adaptability and fault tolerance, which is suitable for space rope network capture system. In addition, the above analysis also applies to the use of rope control rope satellite formation system.
