摘　　要：采用ABAQUS软件对基于热压成型制备的玻璃纤维增强树脂/镁合金叠层板成型后的层间残余应力和变形位移进行了模拟分析。结果表明:叠层板的粘接类型不同,其成型后的层间残余应力和变形位移分布存在明显差异,其中直接粘接叠层板的最大等效应力约为85.5 MPa,其层间残余应力和变形位移主要分布于叠层板边缘,并向层板中心呈梯度递减;而间接粘接叠层板的最大等效应力约为74.2 MPa,其层间残余应力和变形位移主要集中于沿x轴和y轴的中心地带,且呈十字形分布。两种粘接类型叠层板的等效变形位移量相近,数值较小,呈微米级。The residual stress between layers and deformation displacement of glass fiber reinforced resin/magnesium laminates based on hot pressing were simulated and analyzed by ABAQUS software. The results show that the distribution of residual stress between layers and deformation displacement are obviously different with different bonding types. The maximum equivalent stress of direct bonding laminates is about 85.5 MPa, and the residual stress and deformation displacement are mainly distributed at the edges of laminates, and the gradient decreases towards the center of laminates. The maximum equivalent stress of indirect bonding laminates is about 74.2 MPa, and the residual stress and deformation displacement of the laminates are mainly concentrated in the central zone along the x-axis and y-axis, and are distributed in the shape of a cross. The equivalent deformation displacement of the two bonding types laminates are similar and both are small,which is micron level.
