摘要针对弹丸起始扰动会影响坦克行进间射击密集度问题，建立身管柔性的坦克行进间发射动力学模型；考虑弹丸动不平衡及质量偏心、弹炮相互作用、弹炮间隙，建立坦克行进间射击弹丸膛内运动方程；编制行进间射击的坦克发射动力学仿真程序，获得某坦克行进间射击弹丸膛内运动规律及千米立靶密集度，并试验验证仿真结果。该结果可为提高坦克行进间射击精度提供理论基础与仿真手段。

Abstract：The ability of high first round hit probability during marching of the tank is required by modern war. The flexible effects of the barrel have great influence on the launch process, and the initial disturbance of the projectile is the premier factor which takes effect on the marching fire accuracy. The dynamic model of the tank (flexible barrel) was established; considering the mass eccentricity and the dynamic unbalance of the projectile, the projectile-barrel interaction and the gap between the projectile and the barrel, the launch dynamics equations during marching were derived. A simulation program of launch dynamics of a tank during marching was compiled, the motion law of projectile in bore and the 1000m vertical target dispersion are simulated, and the results of simulation are verified by tests. This work provides both theoretical foundation and simulation approaches for improving the marching fire accuracy of the tank system.

Key words： flexible barrel of the tank marching fire launch dynamics fire accuracy movement of the projectile in bore
