摘　　要：建立经典内弹道模型,利用MATLAB编写内弹道程序求解出膛压变化规律曲线、弹丸速度变化曲线。通过构建浮动机动力学简化模型,建立动力学方程组,在MATLAB中编写动力学计算程序,将得到的内弹道膛压数据代入,得到浮动机动力学曲线。从仿真曲线可以看出,浮动机能完成基本的浮动循环。该动力学仿真可为其他武器上的弹簧液压浮动机以及弹簧液压缓冲器的设计提供参考。In this paper, a classical internal ballistic model was established, and the variation curve of the bore pressure and the velocity of the projectile were calculated by MATLAB. Then floating dynamic simplified model and kinetic equations were established, and dynamics calculation program was written in Matlab. The data of ballistic gun pressure are substituted into the program, floating dynamic curve was obtained. From simulation curve it can be seen that floating machine can com- plete the basic floating recycling. The dynamic simulation can provide reference for the spring hydraulic floating on the other arms and the design of spring hydraulic buffer.
