| 摘要本文利用各种内弹道理论，对微后坐力自动炮的内弹道过程和发射性能进行了研究和探索。学习归纳了经典内弹道理论、无后坐力火炮内弹道理论以及膨胀波火炮内弹道理论的相关概念和研究成果，在此基础上建立起了微后坐力自动炮的内弹道数学物理模型。 根据现有的条件，初步学习数学仿真分析的理论知识以及研究方法，利用matlab编制了微后坐力自动炮的内弹道仿真程序，并以已知的122mm火炮的构造诸元及装药条件对所编内弹道程序的第一时期（开闩前）进行了验证，仿真结果与实际较为吻合。利用所编制的内弹道程序，以已知的57mm高炮的构造诸元及发射药为数据来源，在其他条件不变的情况下，研究了不同喷管喉部直径对内弹道性能的影响。8981 本文对微后坐力自动炮内弹道仿真分析的尝试对学习熟练掌握内弹道知识以及数学仿真分析的入门是非常有益的。 关键词：微后坐力自动炮，内弹道，仿真，火炮 毕业设计说明书（论文）外文摘要 Title Micro recoil automatic gun engineering research -launch process modeling and simulation This article uses each kind in trajectory theory, has conducted the research and the exploration to the micro recoil automatic gun's in trajectory process and the launch performance. The study induced in the classics the trajectory theory, to have no children in the recoil artillery in the trajectory theory as well as the expansion wave artillery the trajectory theory related concept and the research results, based on this established the micro recoil automatic gun's in trajectory mathematics physical model.According to the existing condition, the primary learning mathematical simulation analysis's theoretical knowledge as well as the research technique, have established the micro recoil automatic gun's in trajectory simulated program using matlab, in and before arranged the trajectory procedure first time by the known 122mm artillery's structure data and the powder charge condition (to unlatch) has carried on the confirmation, the simulation result and tallies actually. Using in trajectory procedure which establishes, originates take the known 57mm anti-aircraft artillery's structure data and the explosive propellant as the data, in the other condition invariable situation, has studied the different nozzles throat diameter internal trajectory characteristic influence.In this article the trajectory simulation analysis's attempt to studies to the micro recoil automatic gun in masters the trajectory knowledge as well as mathematical simulation analysis crossing the threshold is skilled very beneficial.
