摘　　要：建立了坦克动力舱体的温度场数值计算模型和红外特性计算模型,对坦克动力舱体的红外特性进行了理论计算,得到了辐射强度方向图。动力舱体红外特性的计算结果与试验结果的相对误差小于15.6%,基本满足工程设计的需要。研究结果表明,动力舱顶装甲板是主要辐射源,排气百叶窗和排气管附近顶装甲板是坦克的红外辐射特征明显区域。坦克动力舱体的红外辐射主要集中在8-12μm波段。A temperature field numerical analysis model for the computation of the tank power compartment board is set up. The numerical value of infrared radiation feature of the tank power compartment board is calculated in theory And radiation spectrum intensity direction distribution has been acquired. The relative error of the calculating values isless than 15.6% ,and can basically meet the requirement of engineering applications. The study result indicates that the top board of power compartment is the mainly source of radiation. Exhaust shutter and top board about exhaust pipe is the evidence region of IR radiation character of tank. The infrared radiation of tank power compartment board is mainly 8 - 12μm bands.
