| 摘 要： | 本文基于对复合材料孔板主承力接触区的有限元强度分析结果，利用APDL参数化有限元分析技术，以孔板第一主应力S1和X方向上的变形UX的最大值作为目标函数，对孔形参数进行优化。设计出基于应力和变形最小的开口形状，并得出了孔形参数与应力、变形之间的相互关系。

| Abstract: | Based on strength analysis result of main load-carrying zone of composite plate using the finite element method,using APDL,the optimization of the hole size parameters is carried out.The maximal value of first principle stress S1 and displacement in X direction are as objective function in this optimization.The hole shape is designed based on minimal S1 and UX.Also,the influence of hole size parameters on the S1 and UX is obtained. |

| Keywords: | composite materials plate with hole hole shape stress and displacement APDL |
