Abstract In order to investigate the influence of the gun structural parameters in the bullet motion and muzzle disturbance, a model considering the bullet-barrel interaction was set up by introducing virtual substances. The rigid-flexible coupling dynamics equation of the self-propelled gun system was derived. Taking a tracker self-propelled artillery for an example, the system optimization model was obtained in which the initial disturbances of the muzzle and the projectile were regarded as the objective function. As a result, the comparative curves between the experimental data and the calculation result under the same firing condition were obtained, so the optimization result of structural parameters was. The result shows that this model can reflect truly both the system dynamic response and the bullet motion regularity. Besides, the multi-objective model was optimized on the premise of considering the bullet-barrel contact, which provides reference for the launching dynamics research of the self-propelled gun.
