| 摘 要： | 为提高复合材料带孔板的承载能力，对其孔形和铺层进行优化; 基于损伤力学模型建立了复合材料带孔板的仿真分析模型，并验证了其仿真精度; 选用圆孔、三角孔、方孔3种孔形的复合材料板，分别进行了仅孔形优化、仅铺层优化、先孔形优化后铺层优化、先铺层优化后孔形优化4种优化方案，对不同方案优化后的复合材料带孔板进行失效分析。分析结果表明:仅铺层优化对不同孔形复合材料板的失效载荷提升效果(7.6%~13.4%)明显大于仅孔形优化(2.0%~2.9%)，仅孔形优化对三角孔带孔板失效载荷提升幅度最大，仅铺层优化对圆孔带孔板失效载荷提升幅度最大; 同时采用孔形优化和铺层优化对失效载荷的提升效果明显优于单一优化方法，其中先孔形优化后铺层优化方法对不同孔形复合材料板的失效载荷提升幅度最大(11.6%~15.6%); 铺层优化和孔形优化的先后顺序对圆孔带孔板影响最大(相差3.5%)，对三角孔和方孔带孔板影响相对较小; 3种孔形的带孔板中，圆孔带孔板优化后失效载荷提升幅度最大(15.6%)，在实际应用中圆孔带孔板的性能相对较好，且稳定。

| Abstract: | For a larger bearing capacity of composite plates with holes, the hole shape and ply were optimized. On the basis of the damage mechanics model, the simulation analysis model of composite plates with holes was built, and its simulation accuracy was verified. Three kinds of composite plates with circular, triangle, and square holes were selected, and four optimization schemes were applied, i.e., hole shape optimization only, ply optimization only, hole shape optimization first and then ply optimization, and ply optimization first and then hole shape optimization. The failure analysis of composite plates with holes after optimization by different schemes was carried out. Analysis results show that the improvement in the failure load of composite plates with different holes by ply optimization only (7.6%-13.4%) is significantly greater than that by hole shape optimization only (2.0%-2.9%). The failure load of composite plates with triangle holes is improved the most by hole shape optimization only, while the failure load of composite plates with circular holes is improved the most by ply optimization only. When both hole shape optimization and ply optimization are adopted, the improvement effect is significantly better than that of a single optimization scheme, and the improvement in the failure load of composite plates with different holes by hole shape optimization first and then ply optimization is the greatest (11.6%-15.6%). The sequence of hole shape optimization and ply optimization has the greatest influence on composite plates with circular holes (a difference of 3.5%), but has relatively little influence on composite plates with triangle and square holes. Of the composite plates with three kinds of hole shapes, the failure load of composite plates with circular holes promotes the most (15.6%) after the optimization, and the performance of composite plates with circular holes is relatively good and stable in practical applications. |
