航天運載器力學環(huán)境工程技術發(fā)展回顧及展望

A review of studies on dynamic environments of launch vehicles

  • 摘要: 近50年來,航天科技工作者對運載器發(fā)射飛行過程中的力學環(huán)境的認識逐步深入,帶動了相關基礎理論、預示方法、分析工具、試驗技術和試驗設備的不斷發(fā)展。隨著航天技術的快速發(fā)展,對運載器等的設計要求越來越高,火箭經(jīng)受的力學環(huán)境也越來越惡劣,火箭力學環(huán)境預示與試驗技術研究的迫切性日益突出。文章綜合分析了力學環(huán)境預示與試驗技術領域的研究發(fā)展狀況,重點總結了北京強度環(huán)境研究所50年來為解決航天工程中的諸多力學環(huán)境問題所做的具體工作。最后,結合新時期航天項目的工程需求,提出了今后在航天運載器力學環(huán)境預示與試驗技術研究領域的主要研究方向。

     

    Abstract: In the recent 50 years, scientists have accumulated quite a good knowledge on the launching dynamic environment, and developed related basic theories, prediction methods, analysis tools, test technology and test facilities. Due to the requirement both for speedy development and high-level design of the launch vehicle, the importance of the launch vehicle dynamic environment prediction analysis and test technologies is well recognized. The researches on the launch vehicle dynamic environment prediction and test technology are reviewed in this paper. Beijing Institute of Structure & Environment has carried out studies on many dynamic environment problems of space engineering. According to the new requirement of the domestic space engineering, the main research directions in the launch vehicle dynamic environment prediction and test technologies are discussed.
