| With the continuous development of social science and technology,mankind’s exploitation of outer space resources and space launch activities have become more frequent.While achieving achievements in the aerospace industry,the problem of space debris has also followed.The removal of space debris has become a must for all countries.Major research areas to be faced and resolved.Among the various solutions for the removal of space debris,particle beam-based de-orbit technology has attracted more and more attention and attention from space agencies of various countries due to its unique advantages such as simpler use steps,lower use costs,and safer operating steps.Favor,this technology requires the thruster to be able to generate thrust efficiently,have a large overall speed and current,and the particle beam needs to be transmitted as stably as possible.These key technical indicators are all related to the characteristics of the particle beam,so the impact of the particle beam It is very necessary to study the characteristics.This article combines the research projects of the research group to study the related characteristics and transmission characteristics of the particle beam.At the same time,it puts forward a set of design schemes and measurement ideas of the device for measuring the characteristics of the particle beam,and carries out processing and related simulation test experiments on it.The main academic research work of this thesis includes:1.The research background and current status of space debris removal and particle beam characteristic measurement,as well as the definition of plasma and its common basic characteristics are introduced.2.Introduced the relevant theories of space debris removal,as well as the methods and principles of space debris removal commonly used in various countries at present,compared their respective removal principles,and summarized the best removal methods in various situations.3.The transmission characteristics of the particle beam were studied,and the influence of different acceleration voltages on the speed and current intensity of different particle beams was drawn through theoretical derivation and MATLAB software.Finally,the particle beam was also studied through theoretical derivation and CST simulation software.Transmission characteristics in vacuum environment and geomagnetic field.4.A set of pressure sensor array device for measuring the impact force distribution of particle beams was proposed and designed,and its design ideas and related details were introduced.At the same time,it was processed and pre-tested experiments to verify the rationality and usability of the design;finally,it was completed The construction and testing of the experimental platform required for the follow-up formal experiments are presented,and the preliminary experimental ideas and precautions are put forward.5.The research work of this paper is summarized,and the areas that need improvement at present and the follow-up research work are briefly put forward. |
