摘要: 针对非合作目标对接技术的要求和特点,提出了一种以卫星远地点喷管为对接接口的非合作目标拖拉式对接机构方案。设计了拖拉式对接机构的具体结构并建立其三维CAD模型,根据此模型,对机构进行了包络范围的求解;使用ADAMS软件对机构进行了动力学仿真,分析了对接过程中目标星与机械臂的动态特性,分析了对接过程中捕获力与关节受力情况。计算与仿真结果表明,提出的对接机构能够对目标进行有效、可靠的对接捕获,碰撞接触力小于280N,不会造成本体及目标的破坏。与以往对接机构相比,此拖拉式对接机构具有结构简单、可靠性高、捕获范围大、控制方法简单等优点,且机构受力合理,适合作为空间非合作目标对接的捕获装置。

Abstract: According to the requirements of the non-cooperative target docking technology, a type of non-cooperative target drag-and-drop docking mechanism was proposed. The drag-and-drop docking mechanism is more reliable compared to the previous docking mechanisms. A three-dimensional model of the drag-and-drop docking mechanism was established. The range of the envelope space of the docking mechanism was determined. Kinematics and dynamics simulations were performed for the docking mechanism using the ADAMS software, to identify the dynamic characteristics of the docking process between the target satellite and the docking mechanism, and the capture force and the stress on the joints in the docking process. The simulation results show that the drag-and-drop docking mechanism can capture the target satellite effectively and reliably, and is suitable as a potential non-cooperative target docking mechanism.
