摘　　要：应用ABAQUS软件对SiC_p/Al复合材料薄壁板的变形进行仿真研究,得出了载荷施加位置、SiC颗粒体积分数对SiC_p/Al复合材料薄壁板变形及应力的影响规律。结果表明:随载荷施加位置沿约束方向从薄壁板的中间向端部移动,薄壁板的最大变形和最大应力增加趋势越来越明显;随着载荷施加位置距约束端距离的增加,薄壁板的最大变形和最大应力呈增加趋势。随着SiC颗粒体积分数从5%增加到40%,薄壁板的变形和应力均变化不大,当体积分数从40%增加到56%时,应力明显减小,载荷作用位置距离约束端越远,最大变形减小的趋势越大。By using the ABAQUS software,deformation of SiCp/Al composite thin-walled plate was simulated.Influence rules of load applied position and SiC particles volume fraction to deformation and stress of the plate were obtained.Results show that：the maximum deformation and maximum stress increase gradually as the load applied position moving along the constraint direction from the middle of the thin-walled plate to the end.With the increase of distance from the load applied position to the constraint end,the maximum deformation and maximum stress of the thin-walled plate all show a trend of increase.As the SiC particles volume fraction increase from 5% to 40%,the deformation and stress of the thin-walled plate have a little change.When the volume fraction increases from 40%to 56%,the stress reduces significantly.With the load applied position farther from the distant constraint end,the deformation has a more obvious decreasing trend.
