The high first round hit probability during marching of the tank is extremly important in modern war. The flexibility of the barrel has great influence on the launch process, and the initial disturbance on the projectile is the premier factor which takes effect on the marching fire accuracy. A dynamic model of the tank （ with flexible barrel） was established. Considering the mass eccentricity and the dynamic unbalance of the projectile, the projectile-barrel interaction and the gap between projectile and barrel, the launch dynamics equations during marching were derived. A simulation program of launch dynamics for the tank during marching was compiled. The motion law of projectile in bore and the 1 000 m vertical target dispersion were simulated, and the results of simulation were verified by tests. The study provides both the theoretical foundation and the simulation approach for improving the marching fire acctiracy of tank systems.
