摘要
An accurate modeling of gun barrel temperature variation Over tune is important to assess near and the number of shot fires needed to read, cook-off Using lumped parameter methods., an internal ballistics code was developed to compute heal transfer to the gun barrel for gaol ammunition parameters. Subsequently the finite element method way employed to model gun barrel temperature history (temperature variation over time) Simulation were performed for a burst of nine shots and the results were found to match satisfactorily to the corresponding experimental measurements. Wear or erosion of the barrel during a gun fire is very sensitive toward the maximum, bole surface temperature The proposed scheme can accurately simulate gun barrel temperature history, hence unproved it ear calculations can be made with It An important and unique advantage of the developed scheme is that it easily couples internal ballistics simulations with the finite element methods [DOI 10 1115/1 4001740]
