摘　　要：对天线反射面进行热变形计算时，必须已知反射面上节点温度值形成的温度场，它是进行热变形计算的前提条件。文中提出1种热变形分析计算中温度场的求解方法，依据热分析模型中节点温度值形成的温度场，以插值计算及温度场的连续性为依据、以MATLAB作为求解工具，对热变形模型中节点的温度值进行计算。算法具有高的可靠性且具有广泛的借鉴性，可应用于类似的数值估算中。When calculate thermal deformation of antenna reflector, the temperature field formed by the node of reflective surface must be known. It is a prerequisite of the thermal deformation. In this paper, a calculate method of thermal deformation analysis based on the temperature field is proposed. According to the node temperature in the thermal analysis model, nodes temperature in the finite element model of the antenna reflector surface is calculated. According to the continuity of the temperature field and interpolation, aid to MATLAB programming, the algorithm has high reliability and a wide range of reference, it can be also applied to similar numerical estimate.
