摘　　要：通过建立一维内弹道学两相流模型和经典圆管瞬态热传导模型,研究了大口径火炮多发连射过程的瞬态传热特性,并用ABAQUS软件进一步分析20发连射时炮管的热结构耦合场。得到某155mm火炮药室部温度场和瞬态热应力场分布规律,为进一步评测炮管的疲劳裂纹和确定剩余寿命提供了参考。The heat conduction process of a large-caliber artillery firing was simulated by using an one-dimensional two-phase flow interior ballistic model and an one-dimensional tube transient heat transfer model,by which the transient temperature field and thermal stress distribution of the barrel champer of a 155mm gun were calculated by ABAQUS after twenty shots.The results can provide the important basis to evaluate the fatigue crack propagation and to predict the life of gun barrel.
