Abstract：Dynamic bending of tank barrel under multi-source excitation such as random road excitation and projectile-barrel contact force is the key factor that restricts the firing accuracy of the moving tank at present. Based on the harmonic superposition method and the improved L-N contact algorithm, the influence of the road random excitation and projectile-barrel coupling were described. A dynamic co-simulation methodology was used to establish the dynamic model of the moving tank considering the barrel’s flexibility. The dynamic bending of the tank barrel during the projectile in-bore motion under multi-source excitation was calculated and analyzed. The research results show that the dynamic bending of the barrel is less affected by the projectile-barrel coupling effect, and it is mainly a comprehensive performance under the effect of dead weight and road excitation. When revising the firing accuracy error of the high mobility tank, the influence caused by the barrel dynamic bending should be considered comprehensively.
