摘　　要：针对平板形、圆柱形、圆锥形石英灯加热阵列,本文提出一种基于解析法的热流快速计算方法,构建了三种加热阵列的解析传热模型,将石英灯管和试验件表面分别离散化为点光源和接收点,利用辐射传热定律逐点计算各点接收到的热流密度,建立了圆柱和圆锥加热阵列中单支石英灯管照射范围的判断依据,指出了内加热与外加热情况下算法的区别,得到了典型灯管排布下热流分布规律,可以为热试验加热器设计提供指导。A rapid computation method based on analytic method for heat flux of quartz lamp heating array in the plane,cylindrical and conical shape is presented.The analytic models of heat transfer of these three kinds of heating array is established.The surface of the quartz lamp and test sample is dispersed respectively into light source point and receiving point.The heat flux density on every receiving point is computed singly by laws of radiation heat transfer.The criterions of the irradiation range of single lamp in the cylindrical and conical inner heating array were also proposed.The difference of the computation method between inner heating and outer heating is also discussed.The distribution characteristic of typical lamp array is obtained,which can guide the design of heater in the thermal tests.
