摘要
在内弹道物理模型的基础上，利用方向性量纲分析和相似与模化理论，揭示了反后坐装置在火炮射击过程中的物理现象，建立了其相似准则，考虑到其特点作了相应的准则放宽，推导出具有普遍意义的相似公式，达到了用较小模型模拟较大原型装置的目的，具有一定的经济意义。文末以某步枪为模型，某炮为原型，得到了数值分析与试验结果相吻合的结论，这表明相似性分析在火炮领域中占有重要的地位。
Based on the physical model of interior ballistics, with the vector dimensional analysis and similarity theory, the physical phenomena of recoil system are disclosed,similarity rules are set up,corresponding relaxition of rules is made according to the character, similar formula with popular sense are deduced, the target with smaller model to simulate larger prototype is reached, conspicuous economic effects are received. With the help of model and the prototype,the test results are given to rally the numerical simulation,the application of similarity analysis is of great importance to the field of artillery.
