摘　　要：反后坐装置布局对火炮的总体性能有重要影响,为了定量分析不同反后坐装置布局方案,建立了某火炮反后坐装置典型布局方案的有限元模型,对火炮主要架体进行了结构刚强度数值计算和对比分析。研究表明制退机和复进机空间对称布局方案有利于提高火炮刚强度,进一步的非线性有限元动力学数值计算及分析表明,这种布局方案也有利于减小对炮口振动的影响。The arrangement of anti-recoil mechanism has a profound impact on the overall performance of artillery.For the purposes of quantitatively analyzing different arrangement schemes of the anti-recoil mechanism,established was the finite element model based on the typical arrangement scheme of the anti-recoil mechanism with the structural stiffness strength numerical calculation and comparative analysis of the artillery main carriage parts conducted.Results show that the space symmetrical arrangement scheme of recoil brakes and counter-recoil mechanism will help improve the stiffness and strength of artillery.The further numerical calculation and analysis of nonlinear finite element dynamics show that the arrangement scheme also helps to reduce muzzle vibration.
