“…Malfunctioning and end-of-life satellites become debris in LEO [1,2] and orbital refueling, repair, and active debris removal will become crucial to preserving the near-Earth environment for future generations [3,4]. In-orbit capture will play an essential role in these operations, but it is the most challenging step due to its need for closerange maneuvering and contact with the target [5][6][7]. However, most malfunctioning and endof-life satellites are non-cooperative targets that cannot provide useful information actively [8,9].…”

Malfunctioning satellites are generally non-cooperative tumbling objects. Due to their complex tumbling motion, it is essential to stabilize the target within an acceptable rotating range in the pre-capture phase. In contrast to contactless methods, contact methods based on flexible devices are efficient and can generate sufficient operating torque through flexible contact. However, accurate dynamic analysis of the operation is challenging because of two limitations. It is difficult to obtain a high-efficiency description of the large deformation arising from the operating process. Moreover, the contact between a flexible device and a tumbling object is hard to detect efficiently. This paper proposes a method for detumbling a free-floating rotating satellite; it uses a flexible rod to contact the solar array of the target. The absolute nodal coordinate formulation is first applied to a rod-contact detumbling model in simulation to describe the large deformation of the rod precisely with a low computational burden. Next, a two-step method to detect the contact is employed to pinpoint the contact point and speed up the simulation: coarse detection in the contactless phase and fine detection in the contact phase. Finally, the feasibility of the contact detumbling method is verified. In addition, through the further analysis of the contact process, some characteristics of this kind of strategy are studied for the first time.

“…Moreover, due to its high efficiency for structural connections, the ring-rod mechanism is also widely used in practical engineering, including cable-driven system [4], deployable structures [5,6], drive belts [5,7], and continuum manipulators/robots [8,9]. Especially, the space tether-net system [10,11], a novel lightweight and cost-efficient technique for space debris removal [12,13,14,15], usually employs several joint rings to connect tether rods and flexible nets, in order to achieve the closing mechanism in the post-capture phase [16,17,18]. The core of the design of engineering structures, including bridges, railways, cable cars, and tether-net, is a mathematical model that can efficiently describe the nonlinear dynamic interaction between a flexible medium and a moving ring.…”

Mechanical interactions between rigid rings and flexible cables are widespread in both daily life (hanging clothes) and engineering system (closing a tether-net). A reduced-order method for the dynamic analysis of sliding rings on a deformable one-dimensional (1D) rod-like object is proposed. In contrast to discretize the joint rings into multiple nodes and edges for contact detection and numerical simulation, a single point is used to reduce the order of the numerical model. In order to achieve the non-deviation condition between sliding ring and flexible rod, a novel barrier functional is derived based on incremental potential theory, and the tangent frictional interplay is later procured by a lagged dissipative formulation. The proposed barrier functional and the associated frictional functional are C 2 continuous, hence the nonlinear elastodynamic system can be solved variationally by an implicit time-stepping scheme. The numerical framework is first applied to simple examples where the analytical solutions are available for validation. Then, multiple complex practical engineering examples are considered to showcase the effectiveness of the proposed method. The simplified ring-to-rod interaction model can provide lifelike visual effect for picture animations, and also can support the optimal design for space debris removal system.

“…Wang et al [19,20] proposed a design method for a modular reusable locking release device and applied the mechanical stability principle of plant root growth for layout optimization of the locking unit on the bottom surface of a satellite. Lim and Chung [21] studied the dynamic behavior of tethered satellite systems for space debris capture considering a large deformation of the tether. From the perspective of angular momentum distribution, Yoshida et al [22,23] proposed a bias momentum method approaching the phase for space robots to capture tumbling satellites and discussed the impedance matching problem when an impedance-controlled manipulator approaches and collides with a passive target.…”

In this paper, the mechanism scheme and parametric design of a capture and lock system are studied based on the high reliability of locking systems. By analyzing the workflow and boundary conditions of the capture and lock system, a positioning design is carried out by combining it with the layout of a distributed capture and lock system. Based on the error domain for the passive end in the presence of errors in the manipulator, planning for the capture trajectory and configuration of the design for the active end are carried out. The influence of the passive end on the dynamic performance of the system is comprehensively considered to design the configuration of the passive end. According to the structure of the active end, a mathematical model for the capture and lock mechanism is established, and an analysis of the influence of trajectory parameters on the active end is carried out. The layout design of the capture hook for the active end is carried out based on an analysis of the influence of its layout on posture adjustment. The large-tolerance capability of the system layout is verified with a tolerance simulation analysis and a ground simulation capture test.
