摘要采用155口径火炮，建立经典的内弹道模型、火炮身管传热模型、末制导炮弹膛内受热滞留模型，分析末制导炮弹膛内受热滞留的温度场变化。通过对内弹道方程组的数值求解，分析膛内火药气体温度的变化，建立火炮身管传热模型，对火炮身管传热模型进行求解，模拟分析出身管内外壁温度场的变化，在此基础上，建立起末制导炮弹膛内滞留受热的传热模型，求解出弹丸的温度场变化，进行温度场分析。仿真结果对末制导炮弹膛内滞留时的安全性提供了一定的参考价值。同时，模拟的身管温度变化可以在一定程度上对提高身管寿命有一定帮助，也对末制导炮弹中包含的末敏元器件的安全性的分析有也具有部分的指导作用。64270

Title IN THE BORE TERMINAL GUIDANCE AMMUNITION STRANDED THERMAL NUMERICAL SIMULATION Abstract

Adopts 155 caliber artillery, the classical interior ballistic model is set up, cannon gun tube heat transfer model in the bore, the terminal guidance ammunition heat retention model, analysis of terminal guidance ammunition interior temperature field of heat retention. Chamber through the analysis of the interior ballistic equations numerical solution, the gunpowder gas temperature changes within the body tube heat transfer model, simulation was born tube wall temperature changes inside and outside, on this basis, the solution of terminal guidance ammunition interior heating of the heat transfer model, simulate the temperature field of the projectile. Simulation results for terminal guidance ammunition interior stranded when security provides a certain reference value. Can at the same time, the simulation of body tube temperature changes to a certain extent, help to improve the body tube life to a certain extent, also on the terminal guidance at the end of the shell contained in the security of sensitive components analysis have also have some guidance.
