摘　　要：应用非结构化网格离散结构,建立了具有太阳辐射及背景辐射与对流换热的坦克炮身管温度场的简化模型和身管弯曲计算的简化模型,对仅受太阳辐射以及背景辐射与对流换热相耦合的身管温度场进行了计算,求得身管径向的温度-时间曲线,并分析了身管外表面温度的变化规律。以温度场模型为基础,计算了坦克身管的弯曲量与温度场变化的关系,并提出减小此射击误差的措施。该模型对提高坦克射击精度具有实用价值。A temperature distribution simplified model of tank gun barrel under the radiation from the sun and the background conditions is found. A simplified calculating curve model of tank gun barrel is found. We calculated temperature fields under the radiation from the sun and the background, and being coupled with convection. The thermal-time curves on the radial direction. The variations of the outer surface temperature of the gun barrel are discussed,the relation of temperature field and curve about gun barrel. Measure on reducing the firing errors is improved. The model is real values for improving firing accuracy.
