In order to study the influence of the temperature rise of the inner chamber on the dynamic characteristics of the projectile during the continuous firing process of the artillery, the thermal-mechanical coupling finite element model of the projectile and the barrel is established based on the damage effect of the projectile and the ductile damage fracture. The dynamic characteristics of the projectile in the process of squeezing into the projectile after continuous shooting are obtained by calculation, and the influence of different numbers of continuous fire on the movement characteristics and force of the projectile is discussed. The research results show that the temperature response of the wall of the barrel inside the barrel rises in a regular and periodic pulse-like shape during burst shooting; the temperature rise after 7 bursts and 20 bursts has an effect on the movement, force and structural strength of the projectile in the bore. The impact is not obvious.
