摘　　要：为分析惯性炮闩对惯性炮闩式膨胀波火炮膛压的影响,建立了膨胀波火炮的内弹道模型。计算分析了惯性炮闩的质量、惯性炮闩的启动压力和惯性炮闩的最大行程长对膨胀波火炮的膛压影响。计算结果表明惯性炮闩的质量对膨胀波火炮的膛压影响较大,惯性炮闩的启动压力对膨胀波火炮膛压影响较小,惯性炮闩的最大行程长对膨胀波火炮的最大膛压影响很小。该结果能够为膨胀波火炮惯性炮闩的设计与优化提供一定的理论依据。An internal ballistic model of the rarefaction wave gun was established to analyze the influe-nce of inertial breech on the pressure of a rarefaction wave gun with the influence of the mass of the iner-tial breech,the starting pressure of the inertial breech and the maximum movement distance pressure of the inertial breech on the interior pressure of the rarefaction wave gun calculated and analyzed.The calculation results show that the mass of the inertial breech has more influence on the interior pressure of the rarefaction wave gun,that the starting pressure of the inertial breech has less influence on the interior pressure of the rarefaction wave gun,and that the maximum movement distance of the inertial breech doesn't affect the maximum interior pressure of artillery very much.The results can provide a measure of theoretical basis for the design and optimization of the rarefaction wave gun inertial breech.
