摘要
半个世纪以来,宇航科技工作者对卫星发射力学环境的认识逐步深入,从而带动了相关基础理论、预示方法、分析工具、试验技术和试验设备的不断发展。随着航天技术发展步伐的加快,对航天器设计的要求越来越高,星箭力学环境分析与试验技术研究的迫切性日益凸出。本文重点针对星箭力学环境分析与试验技术所涉及的航天器力学环境预示、航天器力学环境试验和星箭力学环境匹配优化等三方面技术的国内外研究进展进行了综合分析评述;指出了三者之间相辅相成、缺一不可的内在联系:预示分析决定着试验的方法和条件,力学试验又反过来验证预示分析的准确性,力学环境预示分析和试验的准确性和有效性为星箭力学环境匹配优化的顺利开展提供重要保障。最后,根据航天工程的需要,提出了今后在星箭力学环境分析与试验技术研究领域的主要研究方向。
In the recent half-century, astronautical scientists are getting increasing knowledge about the launching mechanical environment , and the development on the related basic theories, prediction methods, analysis tools, test technology and test facilities has been boosted. Due to the requirement both in the speedily development and high-level design of the spacecraft, the importance of the satellite-rocket mechanical environment analysis and test technologies is emphasized. In this paper, the research evolution on the satellite-rocket mechanical environment analysis & test technology, which is related to the mechanical environment prediction & test and satellite-rocket mechanical environment fitness-optimization, is summarized. There are closer relationships among the environment analysis,mechanical test and mechanical environment fitness-optimization, which can be described as follows: the test method and test level are determined by the result of prediction. In the meantime, the accuracy of the prediction is also verified by the test. Both the prediction and test provide the guarantee for the mechanical environment fitness-optimization. In the end, according to the requirement of the domestic space engineering, the main research directions in the satellite-recket mechanical environment analysis and test technologies are stressed.
