摘要

网状系绳组件的特性与单个系绳的特性有很大不同。系绳拖曳系统通常建模为单个系绳。这降低了可靠性。本研究建立了一个网系模型，该模型考虑了网固有的灵活性、碰撞和摩擦。模拟了实际的网合过程，建立了系绳拖曳系统的初始状态。研究了网络对系统特性的影响。根据观测资料，推导了空间网系绳拖曳系统的动态参数。仿真结果表明，网系模型中的张力与长度变化率和长度变化率近似呈线性关系。此外，空间网增强了系绳拖曳系统的阻尼。发现轴向刚度与阻尼系数的比值近似为网系索模型与传统单系索模型尺寸比的幂函数，为修正传统单系索模型提供了一种手段。

Characteristics of tethered towing system after net capture

The characteristics of a net-tether assembly differ significantly from those of a single tether. The tethered towing system is usually modeled as a single tether. This reduces the reliability. This study establishes a net-tether model that accounts for the flexibility, collisions, and friction inherent in the net. The actual net closure process is simulated to create the initial state of the tethered towing system. The impact of the net on the system’s characteristics is examined. Dynamic parameters of the tethered towing system with a space net are inferred from observational data. Simulation results indicate that the tension in the net-tether model approximately follows a linear relationship with both the change in length and the rate of length change. Additionally, the space net enhances the damping of the tethered towing system. The ratios of axial stiffness and damping coefficient are found to approximate a power function of the size ratio between the net-tether model and the traditional single-tether model, providing a means to correct the traditional single-tether model.

期刊介绍： The COSPAR publication Advances in Space Research (ASR) is an open journal covering all areas of space research including: space studies of the Earth''s surface, meteorology, climate, the Earth-Moon system, planets and small bodies of the solar system, upper atmospheres, ionospheres and magnetospheres of the Earth and planets including reference atmospheres, space plasmas in the solar system, astrophysics from space, materials sciences in space, fundamental physics in space, space debris, space weather, Earth observations of space phenomena, etc. NB: Please note that manuscripts related to life sciences as related to space are no more accepted for submission to Advances in Space Research. Such manuscripts should now be submitted to the new COSPAR Journal Life Sciences in Space Research (LSSR). All submissions are reviewed by two scientists in the field. COSPAR is an interdisciplinary scientific organization concerned with the progress of space research on an international scale. Operating under the rules of ICSU, COSPAR ignores political considerations and considers all questions solely from the scientific viewpoint.
