摘　　要：概述了超高速撞击动力学的国内外研究背景;从超高速撞击厚板成坑、中厚板侵彻、薄板形成碎片云、模拟实验技术和数值模拟技术5个方面总结了超高速撞击动力学的研究进展情况;分析了超高速撞击对航天器的毁伤效应;给出了航天器的防护要求;讨论了航天器防护结构的方案设计和性能表征.为超高速撞击动力学和航天器防护研究提供技术参考.Hypervelocity impact dynamics and spacecraft protection as an important part of hypervelocity impact technology, is reviewed in this paper. Its research background is outlined. Its research progress covers the following five aspects： making hole in the thick board, penetration in the critical thick board, forming debris cloud from the thin board, experimental simulation technique and numerical simulation technique. The damage effect of hypervelocity imPact spacecraft is analyzed. The spacecraft protection requirements are given, and the project design and performance of the spacecraft protection structure are discussed.
