摘　　要：研究以德国Poroton产品为参比对象,自行优化设计三种孔型结构的多孔砖模型,并且利用通用有限元分析软件ANSYS对它们进行了稳态热模拟分析。结果表明:三种模型砖的孔洞率均大于35%。采用缩小孔间距、增加烧结多孔砖厚度和复合墙体的方法均可以显著降低传热系数,提高保温隔热效果,达到节能65%的建筑设计标准。Three kinds of perforated bricks are optimized and designed considering German Poroton product as reference. Then the steady- state thermal simulation analysis to them is carried out by general finite element analysis software ANSYS. The results show that their porosity is more than 0.35. It could obviously reduce the heat transfer coefficient, enhance the heat preservation effect and achieve the design standard of saving 0.65 energy as well by narrowing the hole spacing, increasing the porous brick thickness and compounding the wall.
