| 中文摘要: |
| 目的 通过仿真及试验对比六种机翼前缘构型，为机翼前缘发图选型提供参考。方法 以某型飞机机翼前缘结构选型设计为例，对其抗鸟撞性能进行分析。通过对比复材蒙皮蜂窝结构、复材蒙皮蜂窝加吸能板结构以及纯金属结构等不同结构形式的质量变化及抗鸟撞吸能特性，发现纯金属结构前缘抗鸟撞性能具有优势。结果 试验数据与仿真计算结果谱型一致，试验曲线应变峰值为0.0108，仿真结果应变峰值为0.0103，两者相差仅5%。结论 仿真计算有效，且符合预期要求。 |

| The paper aims to provide reference for design of wing leading edge by simulating, testing and comparing six kinds of wing leading edges. With the leading edge of a certain aircraft wing as the example, the bird impact resistance was analyzed. By comparing the mass change and energy absorption characteristics of leading-edge configurations made of several different materials, such as composite skin honeycomb sandwich structure with and without energy absorption board, it was found that the pure metal leading edge had advantages in bird impact resistance. The test data was in line with the result of simulation calculation. The peak strain of the test curve was 0.0108 and that of the simulation result was 0.0103, the difference was only 5%. The simulation results are effective and meet the expected requirements. |
