摘　　要：建立了求解正交各相异性材料等效性能的能量法。数值模拟实验中,在材料组分比一定的情况下,通过缩放因子改变单胞尺寸,研究同种蜂窝微结构对结构力学性能影响的尺度效应;同时验证了不同多孔材料微结构构型对结构刚度的影响;在稳态温度载荷的作用下,热变形引起弯曲变形,利用微结构的构型差异和尺度效应共同作用实现结构最大挠度的控制。We establish the strain energy method for solving the equivalent performance of singularity materials of orthogonal phases. During numerical simulation, the scale effects of the microstructure of the honeycomb on its structural mechanical performance was studied through changing the scale factor of its unit cell while the volume fraction of the materials remains unchanged. In addition, we verify the influence of the shape and microstructure of porous materials of various kinds on their structural rigidity. Under stable thermal load, thermal deformation causes bending deformation. Finally, the shape variation and scale utilized to control its maximum deflection. effect of honeycomb mierostruetur under joint action are
