计及火炮运动的内弹道修正模型

摘要

本文利用多体系统动力学的分析方法给出了弹丸及火药气体的运动学公式，推导了计及火炮运动的经典内弹道方程，分析了弹丸在膛内时期的运动和受力，通过联立全炮系统运动微分方程和内弹道方程求解了火炮和弹丸的运动和受力规律，为火炮的结构设计和射击密集度分析提供了理论依据。%Kinetic relationships of projectile and gases are derived using analytical methods in dynamics of multibody systems. Equations of interior ballistics are formulated, in which the motions of gun responses are considered, and the forces acting on the projectile are analyzed. The responses of gun-multibody systems are obtained by solving the differential equations of motion and equations of interior ballistics, which are of value to the structural design and the analysis for density of impact points.
