摘要:
电帆柔索动力系统以太阳风动压为动力源是一种颇具前景的无工质推进方式,由末端质量在自旋运动中产生的离心力带动展开。由于大变形、大转动柔索具有较强的几何、材料非线性,刚体运动与变形之间出现强耦合等特性,为了对柔索电帆展开过程中的整体姿态变化进行准确模拟仿真,本文采用基于有限段离散化方法建立了多刚体加柔性连接的柔索模型,实现了电帆柔索展开机构的柔性体建模。针对不同驱动展开角速度以及末端质量的情况,本文通过分析柔索伸长速率、末端运动相位、绳内张紧力等的变化特点,分析展开过程中柔索动态特性及影响因素。其中驱动角速度影响展开速率以及柔索运动相位的变化,末端随半径的增加产生的离心力也越大,可能使柔索出现反向缠绕的现象;对更大长细比的柔索,增加末端质量能够增加电帆自旋展开的稳定性。本文的研究能够为柔索电帆机构设计、柔索展开控制及帆面保持提供有效的理论参考。
