On the basis of infrared measurementt,he temperature distribution on T-joints of 5A06 aluminum alloy cylinder structure was simulated by finite element method,developing a composite heat source constituted by Gauss heat source on the surface and inner double ellipsoid heat source.
在红外测温实验的基础上,采用由表面高斯热源和内部双椭球热源组成的复合热源,对5A06铝合金筒形结构间断焊角焊缝的温度场进行了有限元数值模拟。
