基于ANSYS火炮身管传热仿真

Simulation Research on Heat Transfer for Gun Barrel Based on ANSYS

火炮连续发射过程中身管内壁温度持续升高会加快身管的烧蚀磨损,为此分析研究影响身管温度变化的射速、环境温度等主要因素。利用ANSYS软件建立火炮身管有限元模型,对身管内外壁的对流传热和身管壁内的热传导进行仿真,计算求解得到了不同射击模式及不同环境温度下身管内外壁温度的变化规律,结果表明射速增大、环境温度越高,身管温度上升越快。研究成果为依据身管内外壁温度控制火炮发射强度来延长身管寿命提供一定的理论依据。

The temperature of inside surface of gun barrel rises steadily during continuously firing which quickens the erosion and wear onto inside surface.Therefore,primary factors that influence the temperature of barrel is analyzed and studied,such as firing rate and environment temperature.The software ANSYS is used to establish the finite element model of barrel,and simulate the heat convection at both inside and outside surface of barrel and heat conduction in the barrel.The temperature-time curves of both inside and outside surface are gotten under different firing modes and different environment temperature.According to the result,the temperature of barrel will rise quickly as firing rate and environment temperature rise.This research supplies certain theoretical reference to the control of firing intensity of gun by the temperature of inside surface or outside surface of barrel so as to extend the barrel＇s life.
