Abstract


The growing number of space debris caused tremendous potential dangers to the future of human space activities, response, many countries have proposed methods and measures for mitigation, electric power cable from orbit is presented in this context to. The electric power cable from the rail by a long metal wire hanging satellite above or below, in the electromagnetic field in the nature of the Games to generate electric power, energy consumption spacecraft in orbit, so that it orbits reduced height, to achieve the purpose of de-orbiting. Most of the current research targeted at the low-Earth-orbit satellites. In this paper, on the basis of previous studies on this further study from orbit. 1) for the electric power cable extending upward from the rail system to study the impact of the electrical power cable end to collect the contact resistance between the sphere and space plasma the deorbit characteristics of the electric power cable. The calculation of the resistance is a crucial step in the electric power cable from the track, it has a direct impact on the size of the current in the cable, in previous studies tend to consider only the resistance of the cable or contact resistance approximate calculation, which is bound to affect the analysis of the electric power cable from orbit characteristics. Established based on the current - voltage relationship of the TSS-1R satellite-powered cable end to collect the contact resistance between the sphere and space plasma formula, and the 1990 model of the 13-order accurate geomagnetic field model and international reference ionosphere , the use of the track six elements of law Simulation analysis of the contact resistance of the electric power cable from orbit characteristics. 2) for the electric power cable extending downwardly away from the rail system the lateral vibration of the electric power cables carried out. Electric power cables in the process of de-orbiting by a number of factors, for example, electric power, gravity gradient force and atmospheric resistance, while electric power cables and has a quality of light, flexible Tai and damping small and other characteristics, and therefore in the subject to external disturbances easy the transverse vibration. Firstly, the use of micro-element method to establish a continuous electrical power cable transverse vibration differential equations and boundary conditions, the continuity equation and the end of the force boundary conditions are second-order nonlinear, time-varying, strongly coupled partial differential equations, that can not be evaluated the analytical solution, this article using the finite element method and Lagrange equations to the a discrete electrical power cable transverse vibration equation and in 13 order to accurately magnetic field model on track six elements method and Runge - Kutta method lateral vibration of the electric power cable simulation and analysis.
