摘　　要：从最基本的牛顿力学出发,系统地推演了分析力学的d’Alembert-Lagrange方程描述,将方程中的广义主动 力分解成外力的广义主动力、保守力的广义主动力和耗散力的广义主动力三个部分,分别对应作用在大口径火炮 炮身上的弹丸发射作用力、复进机的气体势能保守力和炮架弹性的保守力的广义力、制退机液压阻尼的耗散力广 义主动力。这一动力学方程全面系统地描述火炮的发射动力学过程,具有较强的概念操作性。在此基础上,阐释 了三种大口径火炮的创新设计方案,并且进行了广义的创新设计论述。Based on the basic Newtonian mechanics,this paper systematically deduces the description of the d'Alembert-Lagrange equation of analytical mechanics,decomposes the generalized active force in the equation into three parts of the generalized active force of the external force,the generalized active force of the conservative force and the generalized active force of the dissipative force,which correspond to the projectile launch on the gun barrel respectively.The generalized force of the thrust force,the conservative force of the potential energy of the recoil mechanism,the generalized force of the conservative force of the gun carriage,the dissipative force of the hydraulic damping of the recoil mechanism,and the generalized force of the hydraulic damping of the recoil mechanism.This dynamic equation comprehensively and systematically describes the launching process of artillery and has strong conceptual operability.On this basis,3 innovative designs of large caliber artillery are explained,and a generalized discussion is given.
