    摘要:利用ANSYS有限元軟件建立不同孔型及孔洞率的多孔磚有限元模型,采用適用曲線邊界的SOLID95單元進行網格劃分,計算了不同孔型下的應力分布特征和不同孔洞率下的抗壓強度,分析了孔型對多孔磚力學性能的影響、孔洞率與抗壓強度的關系。利用FLUENT軟件針對孔型和孔洞率進行了熱工性能分析。總結出了理想的孔型和合理的孔洞率,有利于指導生產具有合理孔型和孔洞率的多孔磚。

    Abstract:The finite element models of porous bricks with different pore shapes and porous bricks with different void ratios were established by using ANSYS. The mesh was divided by SOLID95 element with suitable curve boundary. The stress distribution characteristics under different void shapes and the compressive strength values under different void ratios were calculated. The effects of void shapes on the mechanical properties of porous bricks,as well as the relationship between void ratios and the compressive strength were analyzed. FLUENT software was used to analyze the thermal performance of the pass and void fraction. The ideal pore type and reasonable pore rate are summarized,which is helpful to guide the production of porous bricks with reasonable pore size and pore rate.
    Key words:porous brick,finite element,pore type,pore rate,compressive strength
