环境因素对枪管温度场的影响
|
摘要
本文研究了在外界有、无风的情况下,枪管外表面与外界环境之间的对流换热系数的选取;采用枪管一维热传导的数学模型,以经典内弹道数值计算结果为基础,编程求解了不同环境温度与不同环境风速时的枪管温度场,拟合了两个典型时刻枪管内壁及外壁最高温度随环境温度及环境风速变化的公式,揭示了环境温度与风速等环境因素对枪管温度场的影响规律。研究结果为深入研究枪管烧蚀机理、枪管结构设计和寿命预测提供了可靠的理论依据。
The selection of the convective heat transfer coefficient under the wind and windless conditions between the external surface of gun barrel and the external environment was analyzed.The temperature distributions of gun barrel under different ambient temperatures and different ambient wind speeds were calculated numerically by programming with the mathematical model of one-dimensional heat transfer of gun barrel and based on the numerical results of the classics interior ballistic.The formulas of maximum temperature of inside wall and outside wall of gun barrel with ambient temperature and different ambient wind were fitted.The regularity of the effect of environmental factors,such as ambient temperature and wind speed,on the temperature distribution of gun barrel was revealed.The research results had great importance for the further studies of gun barrel erosion mechanism and provided the reliable theory basis for the structure design and the life prediction of gun barrel.
