摘　　要：供输弹机构性能是实现大口径火炮自动化与高射速的根本保障。当前,基于反复迭代与相互脱节的大口径火炮供输弹机构设计模式,易使机构性能与精度先天不足且后续难以弥补,造成供输弹机构设计效率低且服役可靠性差。为解决上述问题,借助有限和瞬时旋量理论在机构连续运动与瞬时运动同维解析表征方面的最简性等优势,构建了供输弹机构连续运动的代数化拓扑模型和瞬时运动的解析化性能模型,实现了同一数学框架下供输弹机构构型与性能的一体分析,为大口径火炮供输弹机构的设计奠定了坚实的理论基础,对提升供输弹机构性能与可靠性等方面具有深远意义。The ammunition feeding mechanism′s performance is crucial to achieving automation and a high firing rate for large-calibre artillery.Currently,the design mode of the ammunition feeding mechanism for large-calibre artillery is prone to inherent deficiencies in performance and accuracy due to repeated iteration and mutual disconnection.These deficiencies are difficult to compensate for in the future,resulting in low efficiency and poor service reliability of the ammunition feeding mechanism design.To address the aforementioned issues,an algebraic topology model for the continuous motion of the ammunition feeding mechanism and an analytical performance model for instantaneous motion are constructed,using the advantages of the finite instantaneous screw theory in the same dimensional analytical representation of continuous and instantaneous motion of the mechanism.The study successfully integrates the analysis of the configuration and performance of the ammunition feeding mechanism under the same mathematical framework.The achievement lays a solid theoretical foundation for the design of the ammunition feeding mechanism for large-calibre artillery.The significance of this study is profound as it improves the performance and reliability of the ammunition feeding mechanism.
