摘　　要：针对自动机在连续射击条件下,身管承受高频、高温冲击作用的特点,建立自动机发射过程中身管的热传导有限元分析模型。采用热传导学理论与有限元方法相结合方法,重点分析不同射弹数、不同身管壁厚和不同发射方式下,身管内、外壁温度数据的变化规律。该分析可对自动机身管热容量设计提供一定的指导意义。The finite element analysis model of heat conduction of gun barrel in the process of automatic mechanism firing was established according to the characteristics of gun barrel subjected to high frequency and high temperature impact under the condition of continuous firing.Based on the combination of heat conduction theory and finite element method,the variation of the temperature data of the inner and outer wall of the barrel is analyzed under different projectile numbers,different barrel wall thicknesses and different launching modes.The analysis can provide some guidance for the thermal capacity design of the automatic fuselage tube.
