摘要 航天器力学环境是航天器在整个任务周期内经受的各种载荷作用的响应描述,是直接影响航天器总体设计水平和决定航天任务成败的关键因素.按照任务阶段,航天器力学环境主要分为发射段的力学环境和在轨力学环境.随着我国航天器设计水平的发展,航天器有效载荷对力学环境的要求越来越苛刻,航天器力学环境分析与试验技术已经成为制约我国航天器设计水平的关键技术.本文重点从发射段力学环境分析技术、在轨微振动环境分析技术、力学环境试验技术和航天器振动控制技术等四个方面对国内外近几年的研究进行了回顾,对相关研究进展和成果进行了系统的归纳与阐述.在此基础上,结合我国航天工程的实际需求及航天器发展的趋势,指出未来航天器力学环境分析与试验技术的主要研究方向. The spacecraft mechanical environment is the response description of spacecraft subjected to various loads during the mission process.It is the key factor that directly affects the design of spacecraft and dominates the suceess/failure of the flight mission.The spacecraft mechanical environments mainly include the mechanical environment of the launching process and that on orbit acoording to phases of the mission.With the development of spacecraft engineering,the harsh requirements of the spacecraft payloads to the mechanical environment are becoming more and more urgent,its analysis and test technology has become the key factor restricting the development of spacecraft.In this paper,the research on the mechanical environment analysis technology of the launching process,the micro vibration environment on orbit,the mechanical environment test technology and the spacecraft vibration control technology are reviewed respectively in four apects,and their evolution and achievement are summarized and discussed.In the end,based on the actual requirements of space engineering and the development trend of the spacecraft,the future research directions of mechanical environment prediction and test technology are pointed out.
