摘要: 热源温度场叠加法(简称热源法)是一种用于解决固体温度场问题的简单而又精确的方法,温度场边界的正确处理是使用热源法的前提条件。文章论述了在求解薄壁结构温度场中热源法的应用,重点讨论了镜像热源数量的选取原则,并分别采用热源法与ANSYS有限元分析软件对算例进行了温度场计算分析与比较。结果表明在正确选取镜像热源数量基础上,使用热源求解温度场可以得到令人满意的结果。

Abstract: Heat-source method is a simple and accurate method for solving temperature field on solid.The precondition of the method is to dispose the boundary condition correctly.The application of heat-source method on sheet structure was discussed and the emphasis was how many enantiomorphous heat-sources should be used.The results of heat-source method and ANSYS software for model were compared.
