Abstract:
This paper presents a comparison of the results of field experiments and mathematical modeling of longitudinal and transverse vibrations of the barrel on firing in a quasi-one-dimensional formulation. The validation of the barrel vibration model is carried out according to the data of the rifle cartridges fired from a ballistic barrel. The vibrations of the barrel are detected using a high-speed camera at high resolution and processed with a specific software. The validation shows that the computer model accurately describes the vibrations of the barrel during firing and allows estimating the amplitude and dynamics of the vibrations.
Keywords:longitudinal and transverse vibrations of the barrel on firing, validation of the mathematical model, ballistic barrel.
