To address the negative impact of excessive forces during penetration space debris by harpoon attachment devices, causing damage to rear electronic components, research has been conducted on buffering and energy absorption effects 2A12 aluminum honeycomb. A simulation model for honeycomb crushing was established through alloy quasi-static tests, SHPB dynamic compression tests. The study investigated effect response accelerations in device results show that at launch velocities 29.2 m/s 29.6...
This paper presents an advanced multiple pieces of debris capture method for the tethered space net robot. A novel strategy that integrates redeployment and self-assembly techniques is introduced. With this strategy, robot self-assembles to close pocket quickly maneuvers nearby target debris. Upon reaching its target, redeploys capture. Central approach development a capturing model accurately describes state function deployed incorporates effective dragging counteract bouncing. To enable...
In this paper, a new mission model, called multi-debris active removal with partial debris capture strategy, is proposed. The model assumes that platform only captures part of the scheduled at time and then releases these pieces to disposal orbit. This process repeated until all removed. A genetic algorithm multi-parameter concatenated coding method designed optimize plan strategy. set six 10 are selected demonstrate proposed planning method. result confirms effectiveness provides more...

Aiming at the problem of harpoon attachment harpoons to space debris with aluminum honeycomb as skin in space, this paper studies penetration-harpoon effect three kinds on sandwich plate under low-velocity impact environment by means experiment and numerical simulation. Penetration tests plates were carried out ground wingless, double-winged three-winged harpoons. The results show that more wings harpoon, larger reaming generated during penetration process, stronger ability. A finite element...
Developing conductive hydrogels has led to significant advancements in bioelectronics, especially the realms of neural interfacing and neuromodulation. Despite this progress, synthesis that simultaneously exhibit superior mechanical stretchability, robust bioadhesion, high conductivity remains a challenge. Traditional approaches often resort filler concentrations achieve adequate electrical conductivity, which detrimentally affects hydrogel's integrity biocompatibility. In study, we present...
