摘　　要：用ANSYS程序模拟计算了结构钢、混凝土、铝合金、铜合金和灰口铸铁这五种蓄热材料在不同形状(圆饼状、方片状、球状)、不同尺寸下的热通量和抗压强度。结果显示,铜合金的导热性能最好,灰口铸铁的抗压强度最高;圆饼状导热性能最好,球状抗压强度最高;圆饼状在直径为10 mm时的导热性能最好,方片状和球状的导热性能随着尺寸的增大而减小,三种形状的抗压强度都是随着尺寸的增大而降低。Applying the ANSYS program,the thermal flux and compressive strength of five regenerative materials,structural steel,concrete,aluminum alloy,copper alloy and gray cast iron,in different shapes(round pie,square flake and sphericity)as well as sizes were simulated and calculated.The simulation results showed that the thermal conductivity of copper alloy ranks was the first and the compressive strength of gray cast iron was the highest.Among the three selected shapes,round pie had the best thermal conductivity and the sphericity s compressive strength was the maximum.In different sizes,the thermal conductivity of round pie was first-rate when the diameter was 10 mm and the thermal conductivity of another two shapes,square flake and sphericity,decreased with increasing size,while the compressive strength of the three shapes decreased along with increasing size.
