摘　　要：以多孔铝合金为研究对象,建立了连通孔型泡沫结构和数学模型。采用Ansys workbench软件Steady-State Thermal模块,利用有限元分析法对多孔铝合金进行热分析模拟。结果显示,多孔铝合金温度从受热面到底面呈梯度分布,越靠近各面中心处,温度降低越慢,而靠近各面交接处时,温度降低越快,其最大和最小温度值分别为300℃和263.57℃。多孔铝合金热通量沿温度梯度方向呈非线性变化,最大热通量1.24×105W/m2,最小热通量22.12 W/m2。Using porous aluminum alloy as research object, a connecting groove foam structure and mathematical model was established. Finite element analysis method was adopted to simulate the thermal properties by using Steady-State Thermal module in Ansys workbench software. The results show that the porous aluminum alloy exhibit gradient distribution from the front of the heating surface to the undersurface. The more near the center of the surface, the slower the temperature decreases, but close to the junction of surface to surface, the temperature decreases faster, where the maximum and minimum temperature is 300 ℃ and 263.57 ℃, respectively. The heat flux of the porous aluminum alloy along the temperature gradient direction is nonlinear; the maximum and minimum heat flux is 1.24 ×105W/m2and 22.12 W/m2.
