太空飞行器M/OD失效风险评估模型

Risk Assessment Model of M/OD Failure of Space Vehicle Model

近年来,随着科学技术的不断发展,人类对太空的探索活动日益频繁,安全的太空环境对人类科学技术的发展有着重要作用。太空碎片的日益增多,对在轨航天器的安全构成严重威胁。该项研究利用M/OD风险评估,建立太空飞行器风险评估模型,从M/OD环境模型、碰撞与失效概率计算等方面,对遭遇M/OD碰撞及失效现象进行了量化分析。结果表明,改变飞行器的运行姿态和舱壁,可有效减小遭遇M/OD碰撞的风险。

In recent years,with the continuous development of science and technology,human space exploration activities are increasingly frequent.Safe space environment plays an important role in the development of human science and technology.The increasing num ber of space debris poses a serious threat to the safety of spacecraft on orbit.The risk assessment model of spacecraft was established by using M/OD risk assessment.From the aspects of M/OD environment model,collision and failure probability calculation,the quantitative analysis of M/OD collision and failure phenomena was carried out.The results show that changing the attitude and bulkhead of spacecraft can effectively reduce the risk of M/OD collision.
