【Abstract】 In view of the problem of working internal forces caused by the elasticity of parts and the damper between parts in the firing process, based on the basic concepts of mechanics, this paper presents the deduced formula for the general force of working internal forces. The formula provides a theoretical basis for simplifying mathematical formula symbols in the gun firing dynamics. The internal forces concerned with the non-stiff parts such as recoil mechanism and the friction torque between upper carriage and lower carriage are studied. This paper lays a foundation for explaining the errors in the theoretical calculation of gun firing dynamics.更多还原
